REPORT OF SUB-COMMITTEE ON SYMBOLS AND DEFINITIONS

Introduction The present sub-committee continues the work of the previous sub-committee which was under the chairmanship of Professor Kerisel. The previous sub-committee completed the list of symbols and definitions which is printed in the 5rd edition (1967) of the eight language lexicon of "Technical Terms, Symbols and Definitions" published by the Swiss Society. The present members of the sub-com ittee are: Dr. H.Q. L,F. Golder Cooling (Chairman) - Great - Canada Britain Mr.Dr. L.A.I, Jurgenson Johnson -- U.S.S.R,U.S,A. Mr. Ch.E. Sandegren Schaerer - -Switzerland Sweden Dr,Prof. G. E, Ter-Stepanian Schultze - W.Germany - U.S.S.R,

Specialty Session No.11 Mexican Conference The work of the new sub-committee really startsd with the organization of the Specialty Session on 'Terminology' at the International Conference in Mexico in 1969. This session was chaired by Prof. Kerisel, the writer acting as secretary. A very short report on this session was written for inclusion in the Proceedings of the conference. Later a transcript of the tape re cording of the session was made and a copy was offered to everyone who was present at the session or who had corresponds d with the secretary about the session. Copies of this transcript are still available. Several matters arising from the session are still to be discussed by the sub-committee. These are listed below under "Future Work". Lexicon The eight language lexicon, produced through three editions by the Swiss National Society is a major contribution to our subject. Several workers have pointed out however that some of the translations are not correct in all languages. In many cases this arises because the English word has more than one meaning. One of the tasks of the sub-committee is to correct these ambiguities and at the same time to add further technical words to the word list. It has been agreed by the members that a) words which are non-technical, or which can be found in any general dictionary should be deleted e.g. abrupt, acid. b) where related words are listed, they should be listed together and marked as e.g.'noun' 'verb' absorb or 'adjective' - v absorbentabsorption -- a.n c) where the English word can be misunderstood or has two or more meanings it should be defined in English. The definition should be translated into the other languages and the appropriate word chosen. e.g. aeolian 'a' - formed by wind action aggregate 'n' - mineral particles used to make concrete d) new words should be considered from closely related disciplines, or arising from new techniques. e,g. adobe, argillite, acoustic. It has taken some time to arrive at these ground rules. The existing word lists are now being circulated letter by letter to all members for their comments. When these are received they are correlated on a special form. The chairman's recommended action based on majority opinibn (or on the opinion of the member who speaks a particular language) is added and the list is sent out again for comment or objectluns. Letter A is practically finished, B, C and D are ready for final circulation. The last letters sent out took us up to L. Now that the method of operation is working it is hoped to proceed more quickly with the remainder of the alphabet. The executive committee is asked to consider the advisability, timing, finance and organization of'a possible fourth edition of the lexicon, S.I,,Systeme International A matter clearly within the duties of the sub-committee, and which was first raised by Dr. Northey of New Zealand, is which system of units should be used by the International Society. Dr. Northey pointed out that when New Zealand, Australia and Great Britain changed from the foot, pound, second (f.p.s.) system they would use the 'Systeme International' (S.I.). This is not the same as the centimetre, gram, second (c.g.s.) or the metre, kilogram, second_(M.K.S.) systems used by most countries which have used the metric system of units for years. There are two differences. In the S.I. the kilogram is used as a unit of mass, and the Newton is the unit of force (and therefore comes into the units of stress and pressure), a Newton being that force which willThe givesecond a mass difference of one iskilogram that the an S.I. acceleration uses multipliers of one ofmetre 105 perand secogd 10' to moveper second. from one unit to the next greater or smaller e.g, l 1kilogram mvtru = =1 1Lum gram L x10-. lO5 Our society must adopt some standard (if interim) policy on the use of units. A letter was circulated to the Chairman of all National Committees asking what the situation was or was likely to be in their country. Sixteen replies were received one of which was simply a formal acknowledgment. Two countries state unequivocally that they are now using S.I. only. They are Britain and Ireland. Poland states that S.I. will be obligatory after 1972. Six countries are committed to S.I. but with reservations and six countries which are already 'metric' state that they have no intention of changing their prcscnt measuredpractice in in thc kgf near or kiloponds future, 1.0. or theymetric will tonnes continue and pressureto uso C.5.D. in kgf/cm OE M.K.S.or tonnes/m2. with force The reservations referred to above are of interest. Spain says S.I. is legal and is to be taught in schools, but c.g.s. and m,kp,s units are also compatible with the law, Spain refers to c.g.s. as only "a subsystem of the S.I." I do not think this is basically true.

New future Zealand engineers agrees will that use S.I.units kilograms should for beforce promoted, and kg/cm but points out that the use of a given system of units is really a matter of personal preference and that all a society can do is to recommend the S.I. units to its members. likePortugal kilograms says thatforce the and tendency kgf/cm2 inand their ton/m cguntry . is to maintain S.I. and derived units Of those countries which will remain M.K.S.

This will probably evolve with practice over a period of years. One fact is clear; only North America is now using the f.p.s. system and Canada is committed to change to the S.I. Further the metric system has been legal in U,S.A. since 1866 and the metre and kilogram have been the legal standards of length and mass since 1895.

Recommendation The sub-committee recommends to the executive committee that the f.p.s. system not be used in the activities of the International Society in future, but that all quantities be given in the S.I. or M.K.S. units. In the case of force or pressure, as an interim, measure, both S.I. and M.K.S. units be given, but 'Kilogram' should not be used as a unit of force, 'kilogram weight' or 'kilopond' being used. 'Bar' as a unit of pressure is acceptable.

Future Work Listed_below are subjects which have been brought to the attention of the sub-committee and with which it is hoped to deal in the next two years. a) Ambiguity in the terms 'modulus' and'co-efficient, 'modulus' having dimensions and 'co-efficient' being a dimensionless number, b) Desirability of correlation of terms used with similar terms in other disciplines e.g. heat flow and seepage; rheology. c) Standardization of grading curves. d) Use of cu and su. e) Co-ordination of terminology with other associations.

In this way this important point could be considered at the next Executive Committee Meeting. In the light of Prof.de Beer's comment, Mr. Meigh agreed to omit from the motion the point concerning a notional minimu number of members. The President confinmed that the motion would not then be contrary to the By-Laws. Mr. Meigh proposed and Dr, Simpser seconded the adoption of the following motion: "In accordance with By-Law 19, the new basis of subscriptions shall be as follows. The amount of the annual subscription of each member country shall be determined by adding together the two following sums: Item 1 Fixed fee per member country, $100 Us Item 2 Athe variable latest sum scale depending of assess on Nations.ment adopted The by classification the United of the member countries into itemthe eight at the groups date ofunder the this approval of this revision of the basis of subscription is given in Appendix A. The amount payable in US dollars is given in Appendix B." Prof. Prakash was unhappy about budgeting for $26,000 as in Appendix B(a) and proposed an amendment to delete this column. This was seconded by Prof. Kézdi and many spoke in support of it. Mr. Meigh stated that the $20,000 budget was based on the assumption that the cost of printing the List of Members should be carried by the next Conference h0Bt 00unbPy¢ On the vote the amendment was carried Hem COI1¢ Dr.Nelson pointed out that S.E. Asia had not been specifically included in Appendix A: he thought it should probably be in Group 3 but he proposed that reference to the United Nations should be omitted. This was seconded by Dr. D'Appolonia. Dr. D'Appolonia then suggested that ISSMFE/UN should be substituted in place of reference to the United Nations and this was agreed. The adoption of the report using column b) in A pendix B in place of column a) was ghen voted upon and this was accepted unanimously. It was thus agreed that the budget should be amended to $20,000 without specifying the individual items and this was carried unanimously. By-Law 19 will now be amended accordingly The Secretary General introduced the 17.

A quotation for printing from Libra Press, Hong Kong, was accepted :Ln September 1971 by the Secretary General, ISSMFE. Editing was carried out by Mr P. Lumb in Hong Kong. Due to his absence from Hong Kong during April to August 1972 about one-third of the first proof and all the final proof was checked by Dr J .D. Nelson and Dr Z-C Moh of A.I.T. :Ln Bangkok. Editorial Work Lists of members of the National Societies were called for :|_n August 1971 with the intention that printing would commence in January 1972. Half of these lists were received in Hong Kong during January but the com plete text was not received until mid-March 1972. The majority of the lists had been well prepared and needed little editing. The total editing time was approximately 12 working days. Printillg Printing commenced in February 1972. Some delay occurred due to lack of diacritical marks for German, Slavic, Scandinavian, Turkish, etc. , alphabets, which had to be ordered by the printer. Two-thirds of the first proof had been checked in Hong Kong by March, and the remaining one-third and the entire final proof checked in Bangkok by July 1972. A total edition of 9,500 copies was printed by September 1972. Despatcgg Packing and despatching was carried out by the pr:l_nter. Lists to societies with small membership were sent by surface mail while lists to societies with large memberships were sent by sea freigmt. Considerable difficulties arose :|.n shipping freight to certain countries from Hong Kong and this caused u.n avoidable delays. Shipping was not completed until January 1973. ' Although the printer had been instructed to insert the Geotechnical Abstracts brochure into each copy of the List of Members, this was uni`ortu.nately not done; the brochures merely being included with the lists.

APPENDIX IV

PROPOSED SCHEME FOR FUIBLICITY AND EXCHANGE OF GEOMECHANICS CO PROGRAMS (to be organized under the auspices of the ISSMFE) Submitted by The Australian Geomechanics Society 1. The Secretariat of the ISSMFE would appoint an Institute to act as a central clearinghouse for publicity on programs. (If necessary, CSIRO, Division of Applied Geomechanics, would be prepared to act :Ln this capacity). The modus operandi of the Scheme would be subject to agreement between the Secretariat and the management of the Institute. 2. Scientists and engineers around the world who had developed, tested and fully documented computer pro grams would be invited to submit them to the Institute together with proforma details regarding the program: Ill e.g. what it does input - output arrangements running costs forms available (listing, cards, tapes) charges for making available name and address of person for further details. The Institute would check that standards of documentation above a defined minimal level were observed by contributors . At least twice a year the Institute would publish booklets containing the accumulated proformas of well documented programs. The Institute would accept no responsibility for the correctness or accuracy of the programs. Any correspondence stimulated by distribution of the booklets would be addressed to the program originators and not to the Institute. The booklets may also contain discussions on any errors or problems with program as reported by users or the originators. The booklets would be distributed to the Secretaries of all National Committees and to any individuals or organizations who would subscribe to the ISSMFE amounts calculated to'cover the running costs of operat ing the service. Thelfact that the service was available could be advertised :l_n the various soil mechan ics journals and newsletters around the world.

APPENDIX V

Between the International Society for Soil Mechanics and Foundation Engineering, the International Society for Rock Mechanics and the International Association of Engineering Geology, is created a permanent coordinating secretariat. This permanent coordinating secretariat is governed by a Committee, composed of the Secretaries General of the three societies. The seat of the permanent coordinating secretariat is to be at Brussels. By unanimous decision of the members of the Committee the seat can be transferred to another city. The permanent coortinating secretariat is to be run in such a way that the expenses can be covered by grants and subsidies of Governments, or other national or international bodies. The Committee of the secretariat gathers at least once a year at the seat of the secretariat, and at such other time when two members of the Committee propose a meeting. The Committee has all powers for deciding the use of the funds put at the disposal of the secretariat. The Committee appoints a secretary, for running the daily activities of the secretariat; he assists without voting right at the meetings of the Committee. The secretary of the permanent secretariat will be invited to all meetings of the executive committees of the three societies. He has only an advising role in these meetings. The mission of the permanent coordinating secretariat in its broadest sense is to promote the coordina tion between the affiliated societies, and to defend their mutual interests. The mission is to be specified in detail by the Committee of the secretariat. Each expansion of the mission has to have the unanimous agreement of all members of the Committee. The official languages of the permanent coordinating secretariat are those of the affiliated societies.

VICE PRESIDEN'I“S REPORT ON NORTH AMERICAN ACTIVITIES 1969 - 1975 D. H. MacDonald - Vice President (North America)

GENERAL The North American geographical zone of the ISSMFE consists of the three countries of Canada, Mexico and the United States of America. Interest in joining the International Society has been exhibited in past years by several other countries in the Caribbean and Central American regions, and specific enquiries have emanated from Panama and the Dominican Republic during the past 4-year period. However, no H2 specific applications for membership have been forthcoming. Membership figures for the three countries are as follows: Janggg 1, 1268. Januagy 1, 1972 Increase or Decrease MexicoCanada 145455 277542 + + 1}4 77 U.S.A.1.428 B20 1,553 754 + - 12586 Numerically, the membership in the zone has grown by 125 in the 4-year period, and the greatest growth has occurred in Mexico. The highlight of the 4-year period since the Seventh Conference in Mexico City was the holding of the Fourth Penamerican Conference on Soil Mechanics and Foundation Engineering in San Ju.a.n, Puerto Rico, from July 14 - 18, 1971. Sponsors of the Conference were: the Soil Mechanics and Foundations Division of the American Society of Civil Engineers (SMFD), the Institute of Engineers, Architects and Surveyors of Puerto Rico, and the Puerto Rico Section of the ASCE. Registration at this Conference was approximately 550. Seven technical sessions covering the fields of standard penetration tests, slope stability in residual soils, allowable settlements, effects of foundation construction on nearby structures, effective ness of cutoffs in foundations and dams, accuracy of field deformation measurements, and the business and practice of foundation engineering. Thirty-three papers were presented and, 'together with the state-of the-art papers, and the panel and other discussions, they constituted a highly successful technical con ference. The meeting also included an enjoyable social program which contributed greatly towards making this conference' another in the gradually developing series of successful Panamerican Conferences. Previous conferences had been held as follows: First Penamerican Conference - Mexico City - September 7 - 12, 1959 Second Panamerican Conference - SaoRio Paulo de Janeirs - July 14 - 24, 1965 Belo Horizonte Third Panamerican Conference - Caracas - July B - 15, 1967 The Fifth Panamerican Conference will be held in Argentina in 1975. Other activities in the North American geographical zone are reported below by the three individual countries constituting the zone.

On June 1, 1972, the Canadian Geotechnical Society was formed as a constituent society of the Engineering Institute of Canada, with Dr G. G. Meyerhof as its first President. At the time of formation its member ship was approximately 400 and it is expected that this will increase to about 500 within a period of one year. Since the formation of the International Society, and at the present time, the role of national society for Canada. has been filled by the Associate Committee on Geotechnical Research of the National Research Council of Canada. Negotiations are, however, currently proceeding so that the newly formed Canadian Geotechnical Society will, within a short time, assume the responsibilities of the national society for Canada. An important accomplishment in Canada in this 4-year period was the undertaking and completion of a study by a committee of the Science Council of Canada entitled "Earth Sciences Serving the Nation". This study dealt with the solid earth sciences, and one of its recommendations has resulted in the formation of the Canadian Geoscience Council, whose function will be to improve communications amongst all societies in Canada interested in the earth sciences. Activity in the geotechnical field has continued at a high level during the past 4 years with increasing interest :Ln the many aspects of geotechnical engineering. In recent years interest in problems involving perma.frost and northern or cold-climate construction has increased greatly. This is particularly re flected :I.n the number of symposia and conferences held in Canada, and a list of the major geotechnical meetingsConference in the country Location is shown below.

In addition to these meetings, several international conferences of considerable interest to geotechnical engineers have been held in Canada. The International Commission on Large Dems held its Tenth International Congress :Ln Montreal from June 1 to 5, 1970, and much of the technical content of the meeting related to earth and rock-fill 'dam and ' foundation problems . Ill Twelfth Congress of the International Society of Photogrammetry was held :Ln Ottawa between July 23 and August 4, 1972. From August 21-30, 1972, the Twenty-fourth Session of the International Geological Congress was held in Montreal, and included in the extensive program were sessions on engineering geology. From July 9-18, 1973, the Twenty-third Congress of the Permanent International Association of Navigational Congresses was held in Ottawa. The ISSI*/[FE was represented at this Conference by Mr C.B. Crawford who will be reporting separately to this Executive Committee Meeting. The series of Trans Canada Lecture Tours initiated many years ago is still continued on an annual basis by 'the Associate Committee on Geotechnical Research, in co-operation with various universities and local geo technical groups. By this means, outstanding lectures by em:Lnent workers in the geotechnical field have been sponsored in many cities throughout Canada. In 1970, the R._F. Legget Award was estblished :Ln honour of Dr R.F. Legget, a former Vice President for North America of our International Society, on his retirement as Director of the Division of Building Research of the National Research Council of Ca.nada. The award is made for achievements of significance to Canada in the field of geotechnical engineering. Recipients of the award have been: Robert Peterson (posthumously) 'in 1970 Robert M. Hardy :Ln 1971 Norman W. McLeod in 1972. The geotechnical community :I_n Canada continues to be served well by the Canadian Geotechnical Journal which is published quarterly by the National Research Council of Canada and is currently :Ln its 10th year.

The Mexican Society for Soil Mechanics acts as the National Society for that country. In recent years its membership has grown rapidly and its activities have correspondingly been enlarged. It sponsored the Seventh Inte1'national Conference of the ISSMFE in Mexico City from August 24-30, 1969. In addition, it sponsors a national meeting at 2-yearly intervals. The Fifth National Conference of Soil Mechanics was held in Mexico City from November 3-4, 1970, and the Sixth such conference was held, also in Mexico City, from November 16-17, 1972. The highlight of the latter meeting was the first lecture in honour of the memory of Nabor Carillo. These lectures will be at bi-annual intervals and the first one was delivered from November 16-17, 1972, by UnfinishedDr Arthur Casagrande, Tasks". a former PresidentI of this Society, who chose as his subject "Reflections on Some The Mexican Society for Soil Mechanics has been responsible over the years for arranging for the issue of a number of excellent publications on geotechnical work carried out by various agencies in Mexico.

However, other organizations such as the Highway Research Board, and the American Society for Testing and Materials are greatly interested in geotechnical engineering and they contribute much through their publications and through sponsorship of meetings. The Soil Mechanics and Foundations Division (SMFD) of the ASCE is interested and active in sponsoring technical programs at ASCE meetings and seminars and conferences elsewhere, sometimes jointly with other technical societies. It publishes its Division Journal at regular intervals, and it is active in promot ing the collection and publication of technical data in a number of geotechnical areas through the work of its committees. The U.S. National Society acted as a co-host for the Fourth Panamerican Conference on Soil Mechanics and Fuundaldon Eug.Luee1~j_ng which was held .Ln San Juan, Puerto Rico from June 14-10, 1971, and reported earlier.

APPENDIX VII

AUSTRALASIAN REEORT Vice President's Report 1262-15 The major change in the organization of the Australian and New Zealand Societies, the two societies comprising the Australasian Region, that has taken place in the period under review is that both have altered their statutes so that they act as national societies of the International Society for Rock Mechanics as well as the ISSMFE. Recently both societies have also agreed to act as natural societies of the International Association of Engineering Geology. The affiliation with both ISRM and ISSMFE was taken as an opportunity to dispense with the over-lengthy SMFE title and both societies have selected the title Geomechanics although this can be regarded as entirely synonymous with the term Geotechnical as commonly employed in Europe. The suitability of the change in name of course remains with the additional affiliation to the IAEG. The broadening of the scope of the societies has brought an increase in membership and has encouraged the activo participation in the Societies' activities by engineering goologists and exports in rock mechanics, both from the Civil and Mining Engineering sides. The consequent meeting of people with overlapping but not entirely common outlook has proved very stimulating at both conferences and local meetings at which technical papers have been delivered. Particularly is this the case of the Australian Geomechanics Society which is jointly sponsored by the Institution of Engineers of Australia and the Australasian Institute of Mining and Metallurgy. ln New Zealand, where mining activity is of lesser importance, the Geomechanics Society, like the previous Soil Mechanics Society, remains under the sole sponsorship of the New Zealand Institution of Engineers but nevertheless, by its broadened scope, has brought a number of engineering geologists into its fold. Both Societies have found the combining of soil and rock mechanics very successful and fully support current moves of the ISSMFE towards co-ordination with the ISRM and IAEG and perhaps consider it unfortunate that such moves were not made earlier and directed more closely towards amalgamation. The mai_n joint activity of the two societies of the region are the holding of regional conferences every four years timed to take place half way between International Sl*/[E'E Conferences. The last was held :Ln Mel-_ bourne :Ln 1971 and was rendered even more successful than usual by the attendance of members of the ISSMFE Executive following its meetings in Sydney. The Australian Society took great pleasure in playing host to the Executive and perhaps obtained some of the benefits of hosting an international conference without incur ring the long months of hard work associated with such conferences. 'I‘he next Australian New Zealand Geo mechanics Conference will be in July 1975 :Ln Brisbane. Preparations for this conference are well under way. ll! A supply of cards publicising this conference has been sent to the Organizing Committee for the Moscow Con ference for distribution to members of that conferenceiie the hope that even more visitors from overseas than for previous Australasian Regional Conferences, will belencouraged to attend the Brisbane Conference. Both societies _hold evening meetings at which technical papers are presented, such meetings being the responsibility of local groups or branches of the Societies centred on the major cities. The Sydney and Melbourne Groups for example, hold approximately nine such meetings per year. Short conferences and one-day symposia on special topics are also organized both by the local branches and., for the more important ones , by the National Committees. With the `incl\1sion of rock mechanics and mining engineering, the number of such short conferences and symposia has increased~in Australia to about four per year. The New Zealand Society publishes "New Zealand Geomechanics News" which contains articles and precis of technical papers given at meetings of the society together with news of local and overseas activities. Through the Institution of Engineers of Australia, the Australian Society publishes the Australian Geomechanics Journal. The Society has recently formed a.n editorial panel for this journal with the aim of maintaining as high a standard of papers as possible. It is hoped that the journal will achieve the same international recognition as journals of some other national societies. E.H. Davis.

APPENDIX VIII

REPORT OF 'IEE VICE-PRESIDENT FOR EUROPE

The Vice-President of a region has to report on the activities of the different national societies of his region during the last four years. However, during the elapsed period the European Societies have suffered losses of such eminent members that they constitute major, although very sad events in the life of these societies, and therefore the audience will understand that I have to start my report with a duty of pious commemoration of those we have lost. I have first to evoke the memory of a past president of our society, Dr Laurits Bjerrum, whose sudden death, while he was :Ln full activity, has been a severe shock for all those who lcnew him personally. It was in London, where he would have attended the Rankine Lecture and also delivered a lecture at Imperial College, that, at the zenith of his life, Dr Bjerrum was taken away from us. He was the beloved disciple of Terzaghi, and in the masterly way he could deliver his lectures, he was the disciple who remembered best all the exceptional qualities of the founder of Soil Mechanics. Also the kindness of his personal contact, and the way he was able to conduct a discussion with the utmost friendliness, without conceding any erroneous _deduct ion or statement, always reminded me of Terzaghi. For the International Society on Soil Mechanics, especially for the European Region and the Norwegian Geotechnical Society, the death of this extraordinary scientist has been a very great loss. The Norwegian Geotechnical Society has decided thesestablishment of a Laurits Bjerrum Memorial Foundation The Foundation‘s income shall be used to further geotechnical research. We are very thankful to the Norwegian Geotechnical Society for this initiative and for the possibility given to private companies and to the offic ial institutions to contribute by donations to the creation of this Foundation to the memory of Dr Bjerrum. The Polish National Society regrets the death of one of the pioneers of Soil Mechanics, Professor Pietowski, who attended practically all International Conferences of our Society, including the first one at Harvard in 1956. with the Russian Society we regret the death of Professor Beresantsev, whose original contributions in our field are lcnown and used the world over. A short time after the Mexican Conference, the Belgian Society registered the loss of an eminent member, Professor Verdeyen. Another tragic event during this period of four years was the mmexpected death of Professor Roscoe, shortly after he delivered one of the most remarkable Rankine Lectures. He formed the Cambridge School of Soil Mechanics, from which a great many scientists have issued, who now continue the work of Professor Roscoe over the whole world. Shortly after the European Conference on Soil Mechanics at Madrid, we were informed of the death of Professor Szechy, one of the most eminent scientists of the Hungarian School, which has done so much in the field of Soil Mechanics. The magisterial book of Professor Szechy will remain as a memory of this charming and most eminent personality, 'I‘he climax of the activities of a Region is of course its regional conference. The Fifth European Con ference on Soil Mechanics and Foundation Engineering was held in Madrid in April 1972. This conference, which was honoured by the presence of the President, Professor Peck, was a real success. ' The Spanish Society should be congratulated for the perfect organisation of the Conference, for' its high scientific standard, and for the perfect publication of the Proceedings. Unhappily shortly before the Confer ence the Spanish Society had to announce the death of Professor Escario, chairman of the Organizing Committee, and one of the world-famous scientists in the field of Road Construction. It was very sad that Professor Escario was not given the opportunity to see the success of his talent for organization. The subject of the European Conference was 'Structures subjected to Lateral Forces' and all aspects of this problem were perfect ly covered in the different sessions of the Conference. The topics were: Session I General theories of earth pressures Session II Stability of rigid structures Session III Stability of flexible structures Session IV Construction problems and case histories. The meetings were held in a building which can be considered as a perfect example of what a, Congress building should be. The Spanish Organizing Committee, and especially Professor Jimenez Salas, should be thanked for the scientific standing of this Conference. The now classical Bankine Lectures of the British Society were respectively given by: the lOth Rankine Lecture in 1970 by the late Professor Roscoe: 'The influence of strains in 'The influence of strains in soil mechanics'. the llth Rankine Lecture in l97l by Professor Jaeger: ‘Friction of rocks and the stability of rock slopes'. the 12th Rankine Lecture :Ln 1972 by Professor Rowe: 'The relevance of soil fabric to soil investigation practice'. the 15th Hankine Lecture in 1975 by Professor Lambe: 'Predictions in soil engineering". All these lectures have been published in the Journal 'Geotechnique'. In Great Britain there has further been in 1970 a Conference on the behaviour of piles, organized by The Institution of Civil Engineers. While mentioning this conference, it is worthwhile to stress that it is nut always easy Lu prevent u. ceJ:l.u.in overlapping' of conferences and su`u_jec Ls, due to Lhe initiative Of institutions which are not directly affiliated to our International Society. In 1975 the British Geotechnical Society organized a symposium on Field Instrumentation. The German Society "Deutsche Gesellschaft fiir Erd- und Grundbau" organized its biennial "Baug'rundtag u.ngen" in Diisseldorf :I_n 1970, and in Stuttgart in 1972. The reports of these conferences, which were atten ded by a. great many scientists and technicians have been published. The great advantage of the German Bau grundtagungen is that they not only focus attention on theoretical and laboratory problems, but they also pay attention to the practical aspects. The "Socie te Francaise de Mecanique des Sols" organized in May 1972 the "Journées francaises de Mécan ique des Sols" about the very important subject 'Comportement des sols avant la rupture - Behaviour of the soil before rupture'. At this conference scientists of practically all French speaking nations were present. It is worthwhile to stress that this conference was honoured by the attendance of Professor Caquet. In October l969 the Czechoslovak Committee for Soil Mechanics and Foundation Engineering, organized in Prague a Conference on 'New advances in Soil Mechancssh Among others a lecture was delivered at that con ference by the much lamented Dr Bjerrum ‘The young Terzaghi and his way to soil mechanics', and a tribute was paid to the memory of Professor Brinch Hansen. At that occasion a memorial tablet was unveiled. placed on the house where the founder of Soi L Mechanics Professor Karl Terzaghi, was born. Among smaller countries, a. very active one in the field of Soil Mechanics is Yugoslavia. In 1969 in Sarajevo an international symposium was organized on 'Civil Engineering Structures resting on soil und roc1€s'. Tho contributions to this symposium have been published by the Academy of Sciences and Arts of Bosnia and Hercegovina, Department of Technical Sciences, Sarajevo. The l2th National Conference of the Yugoslav Society for Soil Mechanics and Foundation Engineering was held in Split in 1971, and the 20th Anniversary of this Society was commemorated in Bled the same year. Another very active country is Hungary. In October 1971 there was in Budapest a symposium on moisture measurement, followed by the European Danube Conference on Soil Mechanics and Foundation Engineering, which was a real example of perfect organiz ation and a plain success. The next "Donau-Europaische Konferenz" will be held in Bled (Yugoslavia) in June 1974 As in many countries there is only one national society covering the fields of Soil Mechanics, Rock Mechanics and Engineering Geology, it is often difficult to determine if the symposia or conferences they organize belong more to the field of our International Society, than to the other two. The Austrian Society hold Colloquia each year in October in Salzburg. For instance the l9th Colloquium was devoted to the problem of 'Moderne Stollen- und Tunnelbau unter besonderer Beriicksichtigung maschinellen Vortriebes ' . The Polish National Society organized in 1970 in Lode a scientific seminar on 'New Problems in the field of Soil and Rock Mecha.nics'. '20 Although I always have to look in the documentation to know if Turkey belongs to the European or Asian Region, it appears; after looking, that it is the duty of the European Vice-President to report that in 1971 was held in Istanbul a Symposium on engineering properties of weathered and jointed rocks. Furthermore on the occasion of the International Conference in Moscow, the Department of Civil Engineering of the Bogazici Univ ersity at Istanbul organizes an International Seminar on Soil Mechanics and Foundation Engineering in the memory of Professor Terzaghi. The Sweizerische Gesellschaft fur Bodenmechanik und Fundationstechnik organized an International Sym posium for underground openings in Luzern in September 1972. The annual meeting of this society in 1969 was devoted to the 'Influence of vibrations on foundations and supporting soil'. The Associazione Geotechnica Italiana had its Conventual Meeting in Milano in 1975. As always the Scandinavian Societies have been very active. The Swedish National Society organized in 1969 several symposia, namely, one on soil sampling, also in 1969, and one on morains (Moran). The Scandinavian Geotechnical Meeting was held in Trondheim (Norway) in August 1972 and was organized by the Norwegian Geotechnical Society. In connexion with the Moscow Conference the Swedish National Society organized a Symposium on Soil Structure on the lst and 2nd August 1973. In principle the initiatives of the National Societies, which-are intended to have a more than nation al audience, should be brought to the attention of the regional vice-president and get his approval. However, this is not always easy as the initiatives are not always taken by the affiliated national societies, but often by other bodies (Academies, Universities, other Societies). In order to obtain a better organization it is strongly recommended that members who know of a given initiative should inform in good time the regional vice-president. Of course the vice-president can only report the activities which are brought to his attention by the national societies involved. I am quite aware that several other activities other than those mentioned in this report have been taken by the societies. The Secretary General has drawn to the attention of the secret aries of the National Societies that they should send a report of the activities to their regional Vice President. However, few societies have followed the suggestion of the Secretary General. Besides special initiatives, the national societies have held local meetings and organized special lectures. It is however impossible to enter into such details. Although until yet in Rumania does not exist a national society on Soil Mechanics and Foundation Engin eering affiliated to our International Society, I received an invitation for the 2nd Conference on Soil Mech anics and Foundation Engineering, organized in Bucaresti in 1972, by the National Council of Engineers. This Conference was devoted to 'Foundation problems in special soil conditions‘. It was to be regretted that Rumania, a country in which outstanding work is done in the field of soil mechanics, was not affiliated to our national society. However during the month of July I was advised that Rumania has submitted its applic ation to be a member of the International Society on Soil Mechanics and Foundation Engineering. The Komitee fir Bodenmechanik und Grundbau in der Deutschen Demokratischen Republik has submitted in due course an application to become a member of our International Society. It has already organized in Dresden in November 1972 an international symposium concerning 'Sohldruckverteilung unter Flachengrindungen bei besonderer Bericksichtigung der Bauwerksteifigkeit' - 'Distribution of soil reactions underneath found ation rafts, with special consideration of the rigidity of the building'. with acceptance of this application, the number of affiliated Societies belonging to the European region will increase from 25 to 24; this is more than half the total number of societies all over the world. with the approval of the regional vice-president, the Swedish National Society will hold in June 1974 at Stockholm a European Symposium on Penetration Testing, and the British Geotechnical Society will hold a conference in Cambridge from 2nd to 4th April 1974 on the problem of the settlement of structures. Of course, the European Region is very proud that the U.S.S.R. National Society has accepted to organ ize the Sth International Conference on Soil Mechanics and Foundation Engineering. The Russian Society has done a tremendous work in preparing this conference. As however, the Conference is not a regional but an international event, the only duty of the vice-president is to mention this initiative taken by the Russian Society. The Vlth European Conference on Soil Mechanics and Foundation Engineering will be organized by the Austrian Society of Soil Mechanics and Foundation Engineering, backed by the Austrian Association of Engineers and Architects. It will be held in Vienna in March 1976, on the occasion of the 50th anniversary of the publication of the book of Professor Terzaghi 'Erdbaumechanik auf Bodenphysikalischer Grundlage'. The theme of the Conference will be 'Deep foundations and deep excavations'. Topics of the sessions will be: Session l: Deep excavations: Stability of temporary and permanent slopes - Dewatering problem-slurry walls , walls with secant piles - bracing; freezing technique. Session 2: Deep foundations: Tunnelling. Session 5: Deep foundations in open pits - Pile foundations - Caisson foundations. During the past four years the opportunity was offered to me to tighten my personal contacts with many national societies and distinguished colleagues. I always appreciated the spirit of friendship and cordiality |21 which exists between the members of our International Society, not only between the older ones who still remember the time of the foundation of our Society by Professor Terzsghi, but also between the younger members.

REPORT OF THE VICE-PRESIDENT FOR AFRICA M. Pimentel dos Santos

The main event during the period was the 5th Regional Conference for Africa on Soil Mechanics and Foundation Engineering. The meeting was held in Luanda, Angola from the 23rd to the 28th August l97l and was followed by an excursion from 29th August to September 4th. A short review of the relevant aspects of the Conference is attached. The activities of the National Societies of Morocco,-Republic of South Africa and Rhodesia are object of short reports also attached. During the period Ghana has organized his National Society. In what concerns both Angola and Mozambique, the most relevant activities were based upon the Civil Engineering Laboratories of Luanda and Lourenco Marques in which a number of lectures and technical courses had been carried out.

CONFERENCE POP AF`RTf‘A ON SOIL MECHANICS AND FOUNDATION ENGINEERING 1 1 Venue and date of the Conference The 5th Regional Conference for Africa on Soil Mechanics and Foundation Engineering took place in Luanda, Angola (Portuguese West Africa), at the Laboratorio de Engenharia de Angola from the 23rd to the 28th August 1971. The presentation and discussion of papers filled l5 working sessions, two sessions per morning and two per afternoon. 2 - Participants B9-national and foreign delegates participated in the Conference, with 33 persons accompanying. From South Atrina there were 41, nf whnm 7 were accompanying; Anstra1ia H, nne accompanying; Brasil N 2 accompanying; U.S.A. 2, one accompanying; England l; Portugal 58, 21 of whom accompanying; Malawi l; Ghana, Tanzania and Jamaica had announced their intention of attending and enroled, however at the last moment their delegates were prevented from coming to Angola for personal or professional reasons. However Ghana took part with three papers. Fl - Opening the f‘nnFe'r~enr~n The opening session was presided over by his Excellency, the Minister of Overseas Territories, Professor Dr. Joaquim Moreira da Silva Cunha, attended by his Excellency the Governor General of Angola, several Provincial Secretaries, the Director General of Public Works and Communications and the Chairman of the 5th Conference Engineer Henrique Novais-Ferreira. 4 - Themes Papers and Respective Discussions 4.1 - The work of the Conference occupied five days, comprising 15 working sessions, 2 per morning and 2 per afternoon. The Conference was organized so as to cover geotechnical problems of outstanding importance which were grouped into 5 themes namely: Theme Tropical and sub-tropical unstable soils Theme Tropical and sub-tropical concretionary Theme Stresses deformation of soils foundation Theme Earthworks Theme Road and slope erosion calculation of same 4.1.1 - Tropical and sub-tropical unstable soils 8 papers* were submitted for this theme, 4 from South Africa, 3 from Portugal and l from the U.S.A. The papers dealt with problems relative to the identification of expansive soils and evaluation of their behaviour, origin of cracking caused by the volumetric unstability, and correlation between geological * - vide index of papers. characteristics and geotechnical properties. The General Reporter was W.R. Mackechnie from Rhodesia, the panel comprised Van der Marwe, Rhodesia, K. Knight, South Africa, J.A. Horta da Silva, Portugal, Milton Vargas, Brasil and A.A.B. Williams,-South Africa. The sessions were chaired hy L.C. Wilson of South Africa, J.M.F. Meireles of Portugal and B.A. Kantey of South Africa. Apart from panel members, contributors to the discussions were made by Aitchison of Australia, B.A. Kantey, G.W. Donaldson, L.Webb, L.C. Wilson, R. Maud and A.A. Williams of South Africa, and B. Martins and Novais-Ferreira of Portugal. In view of the discussion, it was considered to be relevant to progress in this particular field, to know the orientation of soil cracking and diaclase. Aitchison drew attention to the need for future investigation to be directed towards the mechanics of cracked media and not of continuous media. There was considerable discussion of the problems included in the double-oedometer test, concluding that this test, evolved years ago by Knight continues of practical value, but much less for investigation. Knight, Kantey, Barreiros Martins, Webb, etc., took part in this debate. The difficulty in reproducing the range of stress in the laboratory, plus the fact of the expansion or the collapsing settlement being done under complete soaking imposes certain limitations. The question of subdividing the pore pressure into various components was only raised by Horta da Silva, despite the General Reporter having raised it as of great importance for future investigation. Moreover control of suction throughout the oedometer test seems a sine qua non for progress in the study of unstable soil behaviour. With an easy identification of expansive soils in mind by their plasticity index and clay percentage in accordance with the graph published by Van der Merwe in 1964, and taking into account the problem of the occurrence of expansive soils with activity < 0-5 as discussed by Wilson, Horta da Silva proposed the use of the ultimate activity concept. In this new approach IP is determined from values for ML and uP, both determined with the dispersive aqueous solution used to determine the clay percentage. H.l.2 - Tropical and sub-tropical concretionary soils Nine papers* were submitted for this theme, one from South Africa, two from Ghana, four from Portugal, one from Rhodesia and one from the U.S.A. The papers concerned with matters that relate to geological characteristics of concretionary'soils, their fundamental geotechnical properties and their use as construction materials and foundation substratum. The General Reporter was Mountain from South Africa, with panel members F. Hugo and R.R. Maud, South Africa, J.M.F. Meireles from Portugal, C.P. van der Merwe, Rhodesia and B.S. Persons, U.S.A. The sessions were chaired by Novais-Ferreira and A. Rosinha, Portugal, and for H.G. Geed, Rhodesia. Apart from the panel members, the following contributed to the discussion: B. Watt, J. Gregg, Burgers, P.A. Lendin, K. Knight, South Africa, P.G. Wilson, Australia, Milton Vargas, Brasil, and Novais-Ferreira,' Portugal. In view of the controversy arising from the terminology used by different delegates, the General Reporter commented on this, especially concerning ferruginous concretionary soils other soils discussed were silicious and calcarious concretionary soils, Mountain calling attention to the behaviour of gypsoferous ' soils in roads, which in his opinion formed a fourth type of concretionary soils. The problem of autow stabilization of concretionary soils was a further point of discussion. During the debate contributions centred largely on the terminology problem giving rise to even more confusion. In face of this confusion, Burgers idea of the creation of a committee for various participating countries to standardise nomenclature, was aposite. Due to the General Reporters' inability to attend the closing session this was chaired by Knight, who agreed that he himself found that the controversy supported Burgers suggestion, and that confusion seemed to spread to auto-stabilization as well. 4.1.3 ° Stresses and deformation in soils. Foundations Seven papers* were submitted one from Portugal, four from South Africa, one from Thailand and one combined paper Swedish-American. The papers dealt with problems relating to the clay percentage and shear strength, effects of the stress path and of the overconsolidation ratio on the shear strength by vane tests, consolidation character istics of altered tropical clays; foundations on expansive clays and elastic plastic and Visco-elastic behaviour of foundations. The General Reporter was A. Barreiros Martins, Portugal, and panel members were Aitchison, Australia, Novais-Ferreira, Portugal, Webb and Hugo, South Africa, and Milton Vargas, Brasil. The session were chaired by Pimentel dos Santos and J.C. Boavida, Portugal, and Mohamed, Malawi. Apart from the panel members G.W. Donaldson, B. Watt, MacRobertson, L.C. Wilson, H. Weber, and O.K, Steffer from South Africa, E. Brand from Thailand, and A.M. Falcao, Portugal, contributed to the discussions.

”-- Vide index of papers ID In view of the nature of the papers and the current state of the art, it was felt aposite to discuss problems of stress coefficients in soil, their measurement and use in planning foundations, numerical methods for evaluating stress and deformation in foundation soils, non elastic and non-linear elastic properties of african soils, structural characteristics of sub-bases and pavements, buried and surface foundations, load-bearing capacity and the correlation between calculated and actual results by observation of the ground. Aitchison contribution bears mention as to methodology in the study of characteristics and tensile deformation states in soils, and Hatt's mention of the intricate problems with residual soils as well as of the limited value in geotechnical parametres such as plasticity, activity, consolidation, etc., in the light of classical soil mechanics. There was diverse and intense controversy over the latter point. As well as these matters, which took up most of the sessions, it should be mentioned that Webb presented a simples method for calculating subsidence inside embankments, and Donaldson dealt with friction in piles. U.l.N - Earth works Only three papers* were received on this theme, one from Brasil, one from the U.S.A. and one from South Africa, and only three sessions were given to it. The papers dealt with survey of cracked slopes stability design of embankments in tropical countries and geotechnical properties of residual soils originated by alteration of basalts. The General Reporter was A. Burgers of South Africa, with panel comprising G.W. Donaldson, D.J. Watt and K. Knight, South Africa, W. Mackechnie, Rhodesia, and J.A. Horta da Silva, Portugal. The sessions were chaired by Milton Vargas, Brasil, and J.S. Gregg, South Africa. There was discussion by Mac Robertson, K. Steffen, B.A. Kantey, A. van Schalkwyk, L.C. Wilson, from South Africa, E.W. Brand, Thailand, Aitchison and P.G. Wilson, Australia, Milton Vargas and C. Nieble, Brasil, and A. Woods, Rhodesia, as well as from panel members. Each session covered a discrete theme, namely stability of slopes and small earth dams. For the former the General Reporter proposed discussion of various problems related to simplified calculation of rnad-=1nPen pmhankmnnts and gradients. and recognition of soils liable to strength degradation through problems of site-geology, compaction of earth-works, stability, and alterability, of rock-fills were discussed. _ The General Reporter wound up by saying that he thought there had been insufficient time to discuss two so important themes in one. Watt gave an interesting summary of the present level of knowledge on analytical methods based on work by Muller, Hook, Jennings, etc., and including the problem of discontinuous media. Robertson dealt with problems of geological discontinuities, stressing that before choosing an adequate analytical method, one must interpret the geological and geomorphological factors deemed important for each case, and define the ground's most probable slip-potential surface. Nieble discussed the problem ot alterability of rocks, which is considered to be a subject of great importance. In earth-dams, the case being smaller ones only, Aitchison, Williams and Wood mentioned problems of cation-exchange in certain soils. tests for rate of sodium absorption and tor cases uf failure due to deflocculatiun of compacted soils caused by varying electrolitic concentration, a problem already touched on by Horta da Silva. 4.1.5 - Road and slope - erosion Ten papers* were received on this theme, three from South Africa, one from Brasil, two from Ghana, two from Portugal, one from Rhodesia and one British-South Africa papers, which totalled three sessions. The studies piesented dealt with matters relating tn stabilization cf :oils with lime and cement, influence of climatic conditions on the design of pavements, the use of cells for measuring stresses in roads, strength of bases for flexible pavements, behaviour of pavements and correlation between the clay percentage, CBR and density. The General Reporter was Pimcntel dos Santos, Portugal, and the panel was J.S. Gregg, R.A. Smith, and H. Todres, South Africa; R.W. Mackechnie, Rhodesia; J.M.F. Meireles, Portugal. The sessions were chaired by G. Sharp, Rhodesia, K. Knight, South Africa, and M. Falcao, Portugal. Frbm the floor, H.K. Gell, C.P. Van der Merwe, Rhodesia; A.B. Williams, K.A. Clauss, F. Hugo and _ P.A. Loudon, South Africa; Novais-Ferreira and Carlos Silva, Portugal; Aitchisou, Australia, Hilton Vargas, Brasil; bnd M.S.F. Brown U.K., also contributed to the discussion. Based on the nature of the papers, the General Reporter suggested related problems of lime stabilization and of erosion, for discussion. There was discussion by J.M.F. Meireles, Carlos Silva, Novais-Ferreira and Milton Vargas on the erosion problem, dealing with particular cases in Angola and Brasil. Aitchison dealt with the influence of climatic conditions on soil prospecting and pavement calculation including a generalized comparative term, soil suction The remaining discussion covered aspects of design and performance of pavements, not going specifically into lime stabilization except in the case of short reference by Loudon. Williams stressed compaction problems, especially with collapsing soils, and the use of pressure-cells in determining soil stresses. Novais-Ferreira dealt with aspects of the use statistics in soil mechanics. * - Vide index of papers I2‘ 5 Conclusions of the 5th Conference. Norms for drawing up general reports Work finished on August 79th 1971 . The closing session was chaired by Eng. Manuel Pimentel dos Santos, aided by Engrs. Kantey, Mackechnie, and Novais-Ferreira. Engo. Novais-Ferreira spoke first as chairman of the organising committee, giving delegates the conclusions of the ad hoc committee, as follows: l) - nomination of new vice-chairman for Africa - that the nomination be made at the next International Conference de Soil Mechanics in Moscow, l973, Dr. Graft-Johnson of Ghana was proposed, the national society of that country having been recently admitted; 2) venue of the next Regional Conference - after discussion the South Africa National Society for Soil Mechanics and Foundation Engineering undertook to organise the next Regional Conference, and to choose time and place as soon as possible; ` 3) vocabulary for laterites - Eng? Burgers proposed the setting up of a study group to draw up vocabulary for laterites, lateritic soils and ferralitic soils. The delegates agreed with this. 6 - Post-Conference Excursion Upon closure of the Conference work, some delegates and their companions took part in an excursion from August 29th to September Nth, 1971. Visits were made to see roads on lateritic soils in the Quibala-Cela-Nova Lisboa area, roads on expansive soils at Catete, Benguela, Novo Redondo, and foundations in expansive soils. Visits were also made to a concrete dam (Cambambe) and an earth dam (Gove), the latter in the Nova Lisboa area. Annex - Index of papers Tropical and Subtropical unstable soils R.R. Maud D.L.

REPORT FROM RHODESIA 1969-1973 The Rhodesian National Society is the Geotechnical Division of the Rhodesian Institution of Engineers non-members of the Institution being admitted to the Society as Participants. The Division's membership has slowly increased during the period, the number now being about 220 Engineers, Scientists, Technicians and Participants. However, possibly only 10% of this number are actively practising in the Soil Mechanics field, the remainder having only a passing interest. Some 30 evening meetings have been held in Salisbury, with occasional repeat lectures in other cities. Half of the meetings have been formal and the lectures published in 'The Rhodesian Engineer'. Report backs have been given on international conferences in the field. Most lectures have been given by members, with possibly 30% by visiting specialists (mostly on the highway aspects of Soil Mechanics and Geotechnology). Due to the Small numbers of practitioners, local symposia have not been convened. Considerable SUPPOPT was given to the Fourth Regional Conference in Angola, and a contribution was made to the Haifa Conference on Expensive Soils. It is regretted that the lack of visas prevented our representation at the Moscow Conference APPENDIX X

REPORT ON ACTIVITIES IN SOUTH AMERICA IN TH PERIOD 1969-1975. G. PEREZ-GUERRA, VICE-PRESIDENT, S. AMERICA Several important events took place in the region'of the Vice-Presidency, namely: 1 - Fourth Pan-American Conference held in San Juan de Puerto Rico in 1971. 2 - Founding and establishment of the Latin-American Geotechnical Magazine in 1971. 5 - Organization and admission into the International Society of the Chile National Society in 1971. 4 - Second Peru National Conference in 1970. 5 - Fourth Brasil National Conference in 1970. 6 - Second Argentina National Conference in 1970. 7 - Venezuela Lecture Series in 1972.

1 - FOURTH PAN-AM RICAN CONFERENCE Pan-American Conferences are realized every four years, in between the years of the International Con ferences. The first was held in Mexico City in 1959, the second in Brasil (Rio de Janeiro, Sao Paulo, Belo Horizonte) in 1963 and the third in Caracas in 1967. Puerto Rico was elected as the seat of the fourth, it being organized as a joint effort of the Soil Mechanics and Foundation Division of the American Society of Civil Engineers, the Puerto Rico Chapter of the ASCE and the Institute of Engineers, Architects and Surveyors of Puerto Rico. The Conference was held June 14-18 1971, at the Hotel San Juan in San Juan de Puertq Rico. It was attended by 550 registrants and over 150 guests from twenty seven countries, seven of them outside of,the American continent. Both Professor Ralph B. Peck, President of the International Society and Mr G. Perez Guerra, Vice-President for South America, attended the Conference. Dr Peck presided over the Opening Session and acted as ‘discusser-at-large' in all technical sessions. Mr Perez-Guerra presided over the Closing Sess ion and Business Meeting of the Delegates. The key-note address was delivered by Professor T. William Lambe of M.I.T. The theme of the Conference was 'Performance of Earth Structures and Foundations‘, divided into six technical sessions. A seventh, non-technical, session was held, on 'Business and Practice of Foundation Engineering'. The Proceedings of the Conference were published in three volumes by the American Society of Civil Engineers. The first two volumes were distributed at the Conference and the third appeared in 1972. Volume I contains state-of-the-art reports on the six technical sessions; Volume II, papers submitted on the theme of the Conference; and Volume III, discussions, session VII and other activities.

2 - LATIN-AM RICAN GEOTECH ICAL MAGAZINE The first proposal for a regional periodical publication on soil mechanics and foundation engineering was made at the Second Pan-American Conference in Brasil, in 1965. The Venezuela National Society had started in 1960 publication of a Bulletin. From 1960 to 1972 there have appeared thirty-eight issues of the Bulletin, forty to seventy pages each, with technical papers and society news. Owing to it being the only active per iodical technical publication in the region, it was proposed in Brasil to make of that bulletin the divulg ation organ of technical and social activities of Latin-America but the proposal was never implemented. In 1970 the Mexico National Society re-activated the idea of a regional publication on a Latin-American basis, i.e., all South-American national societies plus Mexico, which geographically is part of the North American region. A lengthy consultation followed, conducted mainly by mail, complemented by personal visits of several delegates to countries of South America and Mexico. The Vice-President for North America, Dr D.H. MacDonald, was also consulted and offered valuable opinions and advice. As a result of the consultation all Latin-American national societies concurred in sponsoring a Latin-American Geotechnical Magazine as a region al technical periodical publication and designated Venezuela as publisher. The Magazine was to have a Direc tor and four Advisors, plus a Publication Committee. The first issue, corresponding to the second quarter of 1971, was presented to the IV Pan-American Con ference in Puerto Rico. Within the program of that conference, the Latin-American delegates held a business meeting, presided over by the Vice-President for South America, in which matters related to the publication of the Magazine were considered, brought up to date and resolved upon. By proposal of the delegates for Mexico, approved by the votes of the assembly, it was decided that the Magazine was to be fully bilingual, with versions of all papers both in Spanish or Portuguese and in English. The delegates also appointed Mr J.C. Hiedra L6pez as Director, with residence in Caracas, Venezuela, and as advisors, Messrs. Oreste Moretto (Argentina), Victor F V de Mello (Brasil), Rail J. Marsal (Mexico) and G. Perez-Guerra (Venezuela). These appointments were made for the four-year period to the next meeting of the delegates which will take place at the Fifth Pan-American Conference in 1975 in Buenos Aires. The first four issues of the Magazine` were 129 published with the financial help of the Venezuela National Society, with the expectation that from its second year on the Magazine would pay its way through advertise ments of an inter-American appeal and subscription from America and the rest of`the world. This has not proved feasible with the result that the Director has not been able to publish the fifth issue, for which originals are ready for the printer. The Director has addressed a consultation to the sponsoring countries to get their views and suggestions on how to overcome these difficulties.

2 - CHILE NATIONAL SOCIETY This new member of the International Society was admitted at the Sydney meeting of the Executive Comm ittee, in l97l, by the unanimous vote of the delegates. The Vice-President for South America was charged with the pleasant duty of the Chile representation at the meeting, and on their behalf thanked the Committee for their admittance.

4 - SECOND PERU NATIONAL CONFERENCE The conference took place in Lima in July 1970. The program was organized around the classical headings used in the past by International Conferences" Attendance was numerous with a high percentage of national engineers, with a certain number from other Latin-American countries.

j - FOURTH BRASIL NATIONAL CONFERENCE The Fourth Conference was realized at Rio de-Janeiro in August, 1970. Five main subjects were consid ered: I - Research Techniques - Field and Laboratory; II - General Properties of Typical Soils; III - Earth Pressures and Retaining Structures, Deep Excavations, Subways; IV - Stability of Natural and Man-made Slopes; Brazilianand V - Special engineers. Problems of Design ` and Construction. The conference was attended by a large number of 6 - SECOND ARGENTINA NATIONAL CONFERENCE The conference took place at the city of Cdrdoba in September 1970. The Proceedings of the First Nat ional Conference, held at the city of La Plata, were printed in l97l and sample copies of the volume were circulated at the IV Pan-American Conference in Puerto Rico

]-VEN'EZ'U'ELALEC‘I'U'RESERJIES127£ The series consisted of nine lectures plus two round-table discussions delivered in eight meetings held in four successive weeks from mid-June to mid-July 1972. The series were organized by the Venezuela Soil Mechanics Society, the Venezuela Geological Society and the Venezuela Structural Engineering Society, under the sponsorship of the Venezuela College of Engineers. Its character was inter-disciplinarian and the maximum quota of 100 registrants was amply filled. The lectures dealt with geological features of the city of Caracas, stability of residual soils, found ation criteria, soil-structure inter-action and seismic influence on foundation design.

ACTIVITIES OF THE VICE-PRESIDENT The Vice-President attended the Fourth Pan-American Conference in Puerto Rico and presided over a bus iness meeting of the delegates in which Buenos Aires was elected as the seat of the Fifth Pan-American Confer ence to be organized by the Argentina National Society in 1975. He also attended the Sydney meeting of the Executive Committee of the International Society in August 1971, acting at the meeting as delegate for Chile and Venezuela. In November 1972 the Vice-President visited Mexico upon the gracious invitation of the Mexico National Society and joined Prof. Peck and Dr MacDonald in attending the First Nabor Carrillo Lecture given by Prof. Arthur Casagrande. The Lecture is a bi-annual affair instituted to honour the memory of the great Mexican engineer. The Vice-President had been invited to visit Ecuador on the occasion of the Second Ecuador National Con ference which was scheduled for September 1970, and to give a lecture on expansive soils. This was not real ized as the Conference was postponed. During the period the Vice-President maintained frequent correspondence with the several national soci eties trying to keep up to date on their activities, relaying information received from the Secretary General or requested by them and promoting subscriptions and collaboration to the Latin-American Geotechnical Magazine and the Geotechnical Abstracts. Some correspondence was also interchanged with the Argentine National Society on matters pertaining to the organization of the Fifth Pan-American Conference in Buenos Aires. Contacts were made by mail with groups of engineers from the Dominican Republic, Guatemala and Panama interested in organizing national societies. Ample information was given, providing copies of the statutes of the International and Venezuela Societies, procedures for becoming a member of the International Society and the option to be incorporated into the North America or South America regions. The Secretary General has been kept informed yearly of the activities of the region and both mail and personal communication was maintained with the Vice-President for North America on matters related to the Latin-American Geotechnical Magazine and general policy of the International Society.

APPENDIX XII

REPORT OF COMMITTEE ON DEFINITIONS, SYMBOLS AND TERMINOLOGY Title of Committee The title of the committee seems to be a matter of some doubt. The title given above is that used by the secretary in writing to me but the title given in the agenda is 'Committee on Symbols & Units‘. Other variants have appeared in different places. Now that the major item of the revision of the word lists for the lexicon has been completed, as reported below. it might be helpful to the future committee for the executive to consider the title and perhaps even to state terms of reference. Specialty Session on Terminology and Definitions in Soil Mechanics, Mexico 1969 ' The first task undertaken was the organization of the Specialty Session on 'Terminology and Definitions' at the International Conference in Mexico in 1969. This session was chaired by Prof. Kerisel, the writer acting as secretary. A very short report on this session was written for inclusion in the Proceedings of the conference. Later a transcript of the tape recording of the session was made and a copy was offered to everyone who was present at the session or who had corresponded with the secretarv about the session. Copies of this transcript are still available. As no funds were available this was the most we could do. Several matters arising from the session are still to be dealt with by the committee (see below). International System of units (S.I.) A matter within the duties of the sub-committee, which was first raised by Dr.Northey of New Zealand, is which system nf units should he used hy the International Society. Dr.Northey pointed out that when New Zealand, Australia and Great Britain changed from the foot, pound, second (f.p.s.) system they would use the 'Systeme Tnternatinnal' (S_T,)_ This is nnt the same as the nentimetre, gram, second (c.g.s.) or the metre, kilogram, second (M.K.S.) systems used by most countries which have used the metric system of units for years. There are two differences. In the S.I. the kilogram_is used as a unit of mass, and the Newton is the unit of force (and therefore comes into the units of stress and pressure), a Newton being that force which will give a mass of one kilogram an acceleration of one metre per second per second. The second difference is that the S.I. uses multipliers of 103 and lO'3 to move from one unit to the next greater or smaller e.g. l km = lm x lO3 l gm = lkg x lO'3 Our Society must adopt some standard (if interim) policy on the use of units. A letter was circulated to the Chairmen of all National Committees asking what the situation was or was likely to be in their country. Sixteen replies were received one of which was simply a formal acknowledgment. Two countries stated unequivocally that they are now using S.I. only. They arc Britain and Ireland, Poland stated that S.I. will be obligatory after 1972. |34 Six countries are committed to S.I. but with reservations, and six countries which are already 'metric' state that they have no intention of changing their present practice in the near future, i.e.they will continue to use c.g.s.or M.K.S.with force measured in kgf or kiloponds or metric tonnesk f/c and or pressuretonn s/m2 in The reservations referred to above are of interest. Spain says S.I. is legal gnd is to be tgught' in schools, but c.g.s. and m.kp.s. units are also compatible with the law. Spain refers to c.g.s. as only 'a subsystem of the S.I.' I do not think this is basically true. France suggests giving both units on graphs and also expresses a preference for theI bar I as a unit of pressure, one bar being equal to one decanewton per cmz. West Germany says S.I. units must be used by law from 1977, but refers to the diffic ulty of finding 'handy multipliers for the basic unit 'Newton' which should be suchfas to give convention al figures in conventional statical computations', and says 'Another point, of course, will be how readily engineers will accept new units'. South Africa is committed to S.I. and 'will be completely metricated by the end of l9T3', - they say further however 'it is considered by the engineering profession that in prac tice, for the foreseeable future engineers will use kilograms for force and kg/cmz or tonnes/m2 for stress' New Zealand agrees that S.I. units should be promoted, but points out that the use of a given system of do is to recommend the S.I. units tois reallyits members. a matter Portugal of personal says preferencethat the tendency and that in all their a society country can is to maintain S.I. and derived units like kilograms force and kgf/cmz and ton/mz. Of those countries which will remain c.g.s. or M.K.S. (i.e. NOT S.I ), Turkey does not expect a change in the near future, Hungary is deliberately using c.g.s. and M.K.S. units and awaits the introduc tion of 'Newtons‘ and everything that has to come along with that. Finland will continue to use the c.g.s. system for the time being but expects the new generation will automatically shift over to S.I. as does U.S.S.R. Czechoslavakia uses S.I. with 'one important deviation', which is that supplementary units are used in Civil Engineering practice. These are pond, kilopond and megapond for force and kp/m2 and Mp/m2 for pressure, and p/cm3 and kp/m3 for unit weight. Japan and Greece see no sign of change from the c.g.s. and M.K.S. systems. The picture for the future is one of confusion. Clearly we are going to have with us in Civil Engineering both the S.I. and M.K.S. system for some considerable time in the future. Problems are the size of the Newton (which is small), the 103 multiplier, which becomes 105 for areas and 109 for volumes, and the need to find conveniently sized S.I. units for force and stress. One fact is clear; only North America is now using the f.p.s. system and Canada is committed to change to the S.I. Further the metric system has been legal in U.S.A. since 1866 and the metre and kilogram have been the legal standards of length and mass since 1893. Although it seems that S.I. will eventually win, the sub-committee recommends to the executive committee that the f.p.s. system not be used in the activities of the International Society in future, but that as an interim measure, all quantities be given in the S.I. or M.K.S. units. In the case of force or stress, both S.I. and M.K.S. units be given, but 'kilogram' should not be used as a unit of force, 'kilogram weight' or 'kilopond' being used. 'Bar' as a unit of pressure is acceptable. The matter should be reconsidered at a suitable future time. Fourth Edition of Eight Language Lexicon The eight language lexicon, produced through three editions by the Swiss National Society is a major contribution to our subject. Several workers have pointed out however that some of the translations are not correct in all languages. In many cases this arises because the English word has more than one meaning. The committee has completed the task of compiling a basic word list in English. This list contains 1590 words compared to 1633 in the third edition. However many new technical words have been added, but all non-technical words which can be found in a general dictionary have been deleted. Where an English word can be misunderstood or has two or more meanings, the word has been defined in English in all its meanings. These definitions have been sent to the translators. The idea is that the definition should be translated into French (say) and the appropriate French word be picked to repre sent this meaning. The definitions will not be published. Some of them are open to criticism, but they serve their one purpose. The preliminary suggested word lists contained many words of local usage or from related disciplines Each committee member gave his opinion on each word in these lists. Many of these words were deleted based on the consensus of opinion. The final word lists represent the result of many painstaking hours of work by the com ittee members The translations into the languages other than English are being made by nominees of the appropriate national committees except for German and Swedish which are being done by Prof. Schultze and Mr. Sandegren respectively who are both members of the committee. The translations into French, German and Russian have been completed, though some final typing remains to be done. The Swedish translations are well advanced. We understand that the Spanish translations are comple ted but we have not yet received all of them. We have some of the Portuguese translations. we have no information on the Italian translations.

|35

V/.fy This matter is of some urgency to our Russian colleagues and it would be appreciated if the executive could bring it to the attention of the national committees concerned. The committee has carefully considered the question of what languages should be included in the lexicon A case can be made for including Dutch, and either or both of Czech and Polish. We have discussed this with many friends and it is generally agreed that none ot the existing languages should be dropped. If new languages are added, then the format must be changed since there is no room for additional languages within the existing format. These decisions presumably must be taken by the executive committee in conjunction with the Russian National Committee who have undertaken to print the fourth edition.

Matters outstanding Certain matters proposed by Prof. Kerisel in his report in 1959 have not yet been formally adopted. Other matters are l) a confusion between the terms s and c . Do they mean the same thing? 2) standardization of grading curves 3) a possible ambiguity In the use of the terms modulus and co-efficient I+) co-ordination of our terminology with that used in other disciplines, in particular rheology and heat flow, and 5) matter raised by Prof. Schultze of symbols proposed for quantities in soil mechanics by the International Organization for Standardization which conflict with the symbols already adopted by ISSMFE. Correspondence on all outstanding subjects will be passed to the new chairman.

Conclusion The present chairman retires at this point. I understand that the new'chairman will be Prof. L. Jurgenson. I wish him and his colleagues well and thank the committee members who have worked with me, over the past four years for their efforts and their support.

REPORT TO VIIIth INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING: SUB COMMITTEE ON SOIL SAMPLING

At the Vllth International Conference in Mexico City, a discussion was arranged (as Specialty Session No.l) to cover the following topics: l. The apparatus of soil sampling. 2. The procedures of soil sampling. 3. The logic of soil sampling (from the soil mechanics point of view) and H. The quality of coil sampling. Following the success of these discussions and the publication of the Proceedings of that Session (see Appendix A for list of titles of the 22 papers submitted), it was decided to make the theme for the period between the NIIth and VIIIth International Conferences that of 'Quality in Soil Sampling'. As the proposed first stage in this activity, a Specialty Session was arranged on this topic at the Fourth Asian Regional Conference on Soil Mechanics and Foundation Engineering. The topics to which contributions were invited were as follows: l. The definition of sample quality. 2. Theand definition (ii) of processes contract to attain a specificspecification quality in a soil sample and in (i) technical terms, 3. The measurement of sample quality. Sixteen papers were received (see AppendiX B) and a useful discussion was recorded. The Proceedings have been published. Despite the encouraging response to these Specialty Sessions and despite the evidence put forward in several of the papers to suggest that the highest quality in a soil sample was both predictable and attainable, the conclusion could be reached that there was barely enough enthusiasm - on a world wide basis - to sustain any further enquiry on this topic. It became abundantly clear that in many countries (notably those in which the process of soil sampling follows the preparation of a specification, the calling of bids or tenders, and the acceptance of the most favourable bid ~ usually at the lowesL price), the opportunities for achieving a high quality in soil samples are very limited. The whole technology of soil engineering has adapted itself to the often |36 uncritical nature of the soil samples available for study (as a consequence of the above process). In these circumstances, despite the potential for individual examples of high quality sampling coupled with subsequent studies, the engineering profession as a body appears to be quite satisfied with the Status-quo. The situation is rather different in the case oi' rock _sampling for studies in rock mcchanics. Here the profession is alert to the proper representation - in a sample - of features Critical to pock behaviour. and pertinent to_ a sample. However the field of rock sampling is not within the terms of reference of the su.b-comrnittee. In the light of the discussions reported above it must now be recomended that no further action Should be taken to enquire into aspects of soil sampling relating to normal terrestr1laZ 301125. There is, however, one emerging aspect of soil_ mechanics in which the process of soil sampling is cri1;ieal_ This relates to the earthen materials of the sea floor (including any recently uplifted coastal areas). It appears that there could be considerable economic value in bringing forward at the earliest possible date, a state-of-the-art study together with research contributions on this tQPj_Q_ It is recomended therefore that the attention of the Sub-Committee should be directed towards this area of study. It is proposed that, during the period between the VIIIth and the I>

Asat that chairman time or of on the another Sub Committee occasion on if Soilmore Sampling, suitable. I would be willing to convene such a' specialty session It is my recommendation that this proposed activity should be of an ad-hoc nature only leading to a report at the IXth Conference. Following the presentation of this report on that occasion, the Sub-Committee Julyshould be disbanded. Z975 G.D.

REPORT OF INFORMATION ADVISORY COMMITTEE T0 INTERNATIONAL SOCIETY FOR SOIL MECHANICS AND FOUNDATION ENGINEERING June 15, 1973

The lnfopmetion Advisory Committee (IAC) met in Madrid, Spain, at the occasion nf the European Regional Qenferenfe in April, 1972. Thin Committee, previously named the Abstract Liaison Committee, adopted the new name by resolution at Madrid and upon subsequent approval of the Executive Committee. The Minutes of that meeting are attached 5in¢@ the Madrid meeting, considerable progress has been made as a result of the eflurts of the IAC members. The first of these is the revision of the International Geotechnical Classification System (IGC). The revision is an 0Uf8P0Wfh Of Several years of USS of the IGC bv Nils Flndin (Swedish Geotechnical InsLitute), rin Jupsldd (Norwegian Geotechnical Institute), and Herbert Kuhn (German National Society) with input and review by other members of IAC. The large task of coordinating and completing the Revised IGC was performed by Nils flodin. The revision is made part of this report with the recommendation of IAC that it be acgepted by the Executive Committee and adopted by ISSMFE. Mr. Flodin's comments are also included which #ill explain the nature of the changes and the need therefor (see revised version, May l973, attached). Progress has been made concerning the improvement and marketing of Geotechnical Abstracts/Geodex Retrieval gyetem (GA/GRS), which was named the official information retrieval system of ISSMFE by Executive Committee agtiqn in Mexico in 1969. These efforts are primarily those of Willy Norup (GRS) and Herbert Kuhn (GA), with peripheral assistance from other members of IAC, President Peck, and Secretary Nash. The results of these efforts and cooperation are expressed in Mr. Norup's letter of April 12, 1973 which is made part of this report, The Committee is grateful to Dr. Peck and Dr. Nash for their interest and active support. pp_ peek has prepared lctters of endorsement of GA/GRS which have assisted in the sales promotion of this service, and Dr. Nash has assisted in supporting placement of advertisements at reduced rates. GA/GRS bpgghupeg have been mailed with the ISSMFE Directory with the cooperation of Dr. Peck and Dr. Nash. Secretary Nash has attempted to enlist the assistance of the various national committees in promoting GA/GRS but has not received good response. IAC has been informed of United States National Committee cooperation via announcements in ASCE publications and obtaining of ASCE/SMFD mailing lists, but has not been informed of cooperation from any other national societies. IAC suspects that the major problem is one of lack of funds within the national committees to effect the required promotion. Nevertheless, this committee shares Dr. Nash's disappointment in the lack of cooperation of many of the national`committees; the goals of 50% increase in subscriptions by the end of l97l and lOO% increase by the end of l972 set by the Executive Committee have hardly been met. It has been necessary, therefore, to increase the subscription rate for the combined GA/GRS from $98 (U.S.) to $l78(U.S.) in order to make this a self-supporting enterprise. Several improvements are planned for the GA/GRS system, including increasing the number of key words for retrieval, preparing a manual concerning the use of the system, cross indexing of descriptors that are not key words, and improving the abstracting of paper discussions. If these things are to be done, assistance will be required_of ISSMFE and the national committees to increase the number of subscribers. IAC recommends that the Executive Committee assist in the following manner: l. Insert GA/GRS advertisements and announcements, free of charge, in directories and conference bulletins. 2. Updated national membership lists should be furnished to IAC, as soon as they become available, for use in promotion of GA/GRS. 3. Exert pressure on all national committees to endorse GA/GRS\via their newsletters or technical publications. H. Assist in obtaining reduced rates for advertisements in geotechnical journals (Secretary Nash has already given some assistance in this area). 5. Ask all conference organizers (International and Regional) to forward lists of participants and their addresses to IAC for use in promotion of GA/GRS. It is hoped that the Executive Committee will find this report informative and constructive. The Information Advisory Committee looks forward to the Executive Committee's response and direction. Respectfully submitted, Joseph M. deSaluo, Chairman Nils Flodin, Jacques Florentin, Ivan Sovinc, H. Petermamn, Herbert Kuhn, Willy Norup.

AUGUS'1‘.6. 1973 was among the best, with a keen sense of proportion, judgment, practicality, and economics. Yet, he was enormously curious about fundamentals and pursued the science of soil mechanics with remarkable success. He saw, perhaps more clearly than anyone other than Terzaghi himself, the interrelationships between art and science, theory and practice, field observations and laboratory studies. He was indeed a complete engineer as he was a whole man. He was also an outstanding educator, for he made his Institute truly Participants the finishing school of soil mechanics where many of our ablest young people were exposed to his outlook and his zeal.

They are two-e olution, single-solution and gas silikatization, resinization by means of car bamid resins with hardeness, the use of clay silicate alumosilicate tamping solutions, the compositions of cement-clay solutions substi tuting oemsnt-sand solutions and some others previously used, including the use of elect ric osmos. The fields of most rational use of these methods are determined. The above said methods of soil stabilization were repeatedly employed in foundation const ruction, in driving underground workings and for anti-filtration curtains. Thus,accorc`Ling to Soviet scientists' suggestion there was successfully achieved an anti-filtration cur tain of the high_rise Asuan dam where 1800 thous.cu.m. of soil was stabilized. The investigations in the field of soil dynamics carried out in the USSR have ensu red the working out and the use in construc tion of vibration methods. By means of vib ration methods tens of thousands piles and about 400 thous.tons of sheet piling were driven and more than 100 thous.tons of sheet piling, pipes and beams were pulled out. At the construction of bridge supports this method allowed to substitute thin-walled shells for coffers and pressurized caissons. The vibration method is successfully used for driving engineering and geological bore holes. By means of a vibration hammer more than lOO million running m. of shallow prosp ecting boreholes were drilled for the evalu ation of soil conditions on construction sites. Hundreds of running kilometres of oil and gas boreholes were bored with the use of the vibration method; 3u.l.enl.lf_i.c J.-eseai-uh .Ln the field of foun dation dynamics made it possible to work out methods to design foundations for machinery and other plants exciting dynamic loads as well as contributed to improve methods of designing buildings and structures for const ruction in seismic regions. Quite important is the problem of buildings and structures construction in regions with intensive mining. As a result of investiga tions and generalization of the experience of construction over mining workings there were worked out rational structures of buildings and foundations of either rigid or yielding structural schemes, design methods of forces acting in buildings with earth surface settle ment,violation economic of service structural fitness measures of earlier against built buildings where at present there are mining workings under them. A number of recent scientific studies conduc ted by Soviet specialists in the field of soil mechanics and foundation construction is described in reports presented by partici pants of the International Congress. Ne are hoping that studies by Soviet scientists and engineers will make a_ contribution into a generalimatter of the development of building science,

REPORT OF THE QSUBCOMMITTEE ON THE EXHIBITION OF EQUIPMENT organizedAn exhibition in the of lobgy a paratus of the from bentral abroad State was Concert Hall in the Rossia hote1,where only moderate-sized items could be exhibited,such as posters, stands, prospectuBes and small apparatus. Twelve firms from nine countries participa ted in the exhibition. The total area taken up by the exhibits was about 150 square metres. In organizing the exhibition the Sub-Conv mittee set the following aims and problems: l. To invite firms from many countries to take part in the exhibition, to aquaint the Conference participants with various design solutions in the field of foundation enginee ring. 2. To aqusint the Conference participants with achievements in the investigation of soil properties, paying especial attention to field techniques and pertinent instrumen tation, and also with certain laboratory equ ipment, used for evaluating the strength an deformative properties of soils in foundati onThese engineeriug. aims were fulfilled. T Posters and prospsctuses on foundation en gineeringrms: Geosonda were (Italy),exhibited Baugrund by the (Germanfollowing e fi mocratic Republic) and Terrafigo A.B., (Swe den). Fifteen per cent of the exhibition area was taken up by these exponents. The main part of the exhibition area (about 84%) was occupied by posters, samples and prospectuses on instruments, characterizing the achievements reached in the field of soil mechanics and in the observation of deforma tions in the bases of structures. In this section of the exhibition, the fol lowing firms exhibited their products: Gectech.Co.E1mbren (Sweden) Kyowa Ehsctro nic Instruments Co.Ltd. Japan),Gooda (Holland) Telemac (France),Bovac Switzerland),Geonor (Norway),Engineer1ng Laboratory Equipment Ltd. (England) and the University of Manches ter (England). The firm Geotechnical Abstracts (Federal Republic of Germany) demonstrated various forms for taking into account and registering investigation data, and statistical methods of processing these data. Many participants and guests of the Confe rence attended the exhibition.
