The fee- vibration cycles, regardless of the initial magnitude of Chang, Der-Wen (Editor for Asia) shear strain amplitude, are fully attenuated after 0.08 Davis, Heather (Editor for Africa) seconds. Since the initial shear strain amplitude is Gonzalez, Marcelo (Editor for South America) lowest under the highest suction state, s = 400 kPa, Jefferis, Stephan (Editor for Europe) this is strongly indicative of lower material damping at Leung, Anthony Kwan (Editor-in-Chief) higher suction values, which can be attributed to the Ng, Charles Wang Wai (Ex-officio) increase in stiffness with increasing suction.

Suction-controlled triaxial testing A servo/suction-controlled double-walled triaxial system is used for unsaturated soil testing via either axis- translation or vapor transfer technique, as shown in Figure 3. Main features of the triaxial system include: 1 – Auto-RH system; 2 – Gas bubbler, desiccant, and temperature probe; 3 – Core triaxial system; 4 – Automated volume-change device; and, 5 – Automated flushing device. Recent efforts focused on suction- controlled testing of a relatively dense soil with a natural tendency to experience dilatancy and post-peak softening as it approaches critical state. Statically compacted specimens of silty sand were tested in the low-to-medium suction range (50-750 kPa), via the axis-translation technique, as well as the higher suction range (20-300 MPa), via the vapor transfer technique.

Figure 4 shows the volume-change response of compacted SM soil from suction-controlled axisymmetric shearing under constant matric suction, s = 50 kPa, and initial net mean stress, p = 100, 200, or 300 kPa. Ceramics with 1-bar air-entry values were used to induce a matric suction of 50 kPa. Additional tests were performed on identically prepared specimens using 3-bar ceramics for matric suction of 250 kPa, and 15- bar ceramics for matric suctions of 500 kPa and 750 kPa. Results show a clearly manifest change from compressive to dilatant behavior, regardless of initial net mean stress, as the test soil approaches critical state condition under a constant matric suction even as low as 50 kPa. The amount of dilatancy, as expected, decreases with increasing net mean stress.

Suction-controlled true triaxial testing A servo/suction-controlled true triaxial apparatus is used for testing cubical soil samples, 7.62 cm (3 in) per side, via axis-translation technique, as shown in Figure 5. The apparatus is a mixed-boundary type of cell, with the sample seating on a 5-bar or 15-bar ceramic and between five flexible membranes on the remaining sides of the cube. It consists of a stainless-steel frame, featuring six pressure cavities to accommodate one top and four lateral latex membranes, and one cubical base aluminum piece at the bottom assembly to receive the HAE ceramic and four coarse porous stones. The sample is gently slid in through one of the lateral cavities of the frame, with the membranes acting as the pressure seals between the wall assemblies and the frame, thus transmitting the water-based hydraulic pressure to the top and four lateral faces of the soil.

Figure 5. Suction-controlled TTX device (GCTS Testing Systems; UC-Boulder)

External hydraulic pressure is generated by a computer-driven, model PCP-5000-UNSAT pressure control panel, with independent control of major, intermediate and minor principal stress. A computer driven, model PVC-100-UNSAT pressure-volume control system maintains a constant pore-air pressure through the porous stones at the bottom of the sample. In both panels, model DC-750-5000 Macro Sensors hydraulic pistons are used for measurements of positive (compression) and negative (extension) deformations of the sample in all three principal directions.

Figure 6 shows results from a suction-controlled simple shear (SS) test conducted on SP-SC soil at matric suction, s = 200 kPa, and net mean stress of 100 kPa. During SS testing, the major principal stress is monotonically increased, the minor principal stress is simultaneously decreased in the same magnitude, and the intermediate principal stress is kept constant. Consequently, the major principal strain is observed to be compressive (+), the minor principal strain expansive (–), and the intermediate principal strain is virtually negligible.

Peak strength values from a series of suction-controlled TC, TE, and SS tests, all conducted under same net mean stress of 100 kPa, were used to identify the failure envelopes in the octahedral plane. It can be readily observed the marked effect that matric suction has over the size and positioning of the failure loci, with a significant expansion for s = 200 kPa.

Suction-controlled plane strain (biaxial) testing A servo/suction-controlled biaxial apparatus has been used for testing unsaturated soils under plane strain conditions via axis-translation technique, as shown in Figure 7. The design of its core system is based upon the original Vardoulakis type of apparatus, allowing for direct measurements of normal stresses generated between a soil specimen and two lateral rigid walls during suction-controlled plane strain shearing. Plane strain condition is imposed on the soil specimens by means of two 8-mm thick rigid walls made of Type 304 stainless steel. These walls prevent the specimen from deforming along the intermediate principal axis X2.

The bottom pedestal receives an HAE ceramic and rests on a U-shaped stainless-steel base frame, which couples the pedestal and the rigid lateral walls to a model NKL 6-110 sliding table. Lateral displacements experienced by the specimen in the minor principal axis X3 during plane strain shearing is measured by four Microstrain type DVRTs (differential variable reluctance transducers). The intermediate principal stress along axis X2 is measured via Sensotec type pressure cells installed on each of the rigid lateral walls. The assembly is ultimately placed inside a Wykeham-Farrance pressure cell with a 1.7 MPa pressure capacity.

Figure 8 shows a photograph of a typical failure induced on SM soil sample subjected to suction-controlled plane-strain shearing. A fully developed failure surface, making a 65o angle with the horizontal, can be readily identified from a sample failed under matric suction, s = 100 kPa. A relatively less inclined failure surface, making a 61o angle, was observed on a separate sample failed under matric suction, s = 50 kPa.

Suction-controlled ring shear testing A servo/suction-controlled ring shear apparatus is used for testing residual strength of unsaturated soils under virtually unrestrained torque via axis-translation technique, as shown in Figure 9, including vertical loads up to 8000 N, monotonic torque up to 113 N-m, and three main modules: 1 – Main cell with pneumatic actuator for normal loading and electromechanical rotary actuator for torque loading; 2 – DAS with data reduction software for normal/shear stresses, and average linear/angular displacements; and 3 – Model PCP- 15U pressure panel for suction control via axis-translation. The bottom annular platen receives a full set of HAE ceramics, while the 15-mm (0.59-in) thick sample is statically compacted into the bottom annular platen. A sitting load of 25 N is applied to bring the upper platen in full contact with the top surface of the soil. A pore-air pressure line, from the PCP-15U panel, is connected to the cover plate via a quick connector.

Figure 10 shows the effect of suction on both the peak and the residual failure envelopes obtained from suction-controlled RS testing of compacted CL soil. Results appear to confirm the unique correspondence observed between the nonlinear nature of peak failure envelopes (threshold value of matric suction beyond which they become nonlinear) and the air-entry value of the test soil obtained from SWCC (about 100 kPa for the CL soil). The residual failure envelope, however, remains reasonably linear given the relatively low value of net normal stress applied.

Suction-controlled cyclic simple shear testing A novel Cyclic Simple Shear (CSS) apparatus is currently being implemented for advanced thermo-hydro- mechanical testing of unsaturated soils, as shown in Figure 11. The system will allow for testing under cyclic simple shear conditions for a wide range of controlled matric and total suction states (0-100 MPa). A digital convection heater will also be adapted to the main cell of the CSS core system for thermal conditioning of the pore-fluids. To this date, there is hardly any comprehensive study at the laboratory scale focusing on a thorough characterization of thermo-hydro-mechanical response of unsaturated soils, particularly shear modulus and damping, for a large range of cyclic shear strain amplitudes (0.001% to 1%) and a wide range of controlled suction states and simultaneously controlled thermal conditioning of the pore-fluids. The lack of experimental evidence of this kind is a chief motivation for the present work.

Mr. Soichiro Okawa, the Deputy Head of the diplomatic mission, Advisor of the Ambassador of Japan in the Republic of Kazakhstan and Prof. Loretta O'Donnell, Vice-Rector for Academic Affairs of Nazarbayev University, addressed welcome speeches to the delegates at the opening ceremony of the 1st ENU-HIT Scientific Forum (L.N. Gumilyov ENU and Hachinohe Institute of Technology).

Professor Akira Hasegawa at the opening ceremony said that an exchange between ENU and HIT has a long history. In 1991, Prof. Askar Zhussupbekov visited the geotechnical laboratory of Prof. Nobuchika Moroto from HIT for studying in Geotechnical Engineering. This is the beginning of exchange activities between ENU and HIT. Since then, Prof. Askar gave lectures at HIT and our institute invited ENU graduate students to HIT. In order to improve exchanges between the two universities, on 21st June 2017, a cooperation agreement was signed at ENU. The theme of the forum is Geotechnical Infrastructure for Megacities and New Capitals. Basic social infrastructures, for examples, transportation facilities such as roads and railways, lifelines such as electricity, water, sewer, etc. are very important for enriching people's lives and industries. The foundation of this social infrastructure is exactly the ground. Professor Akira Hasegawa also expressed the hope that research results of participants would be reflected in the geotechnical issues in each region in future, and provide the safety of social infrastructure.

The plenary session was devoted to the construction of underground structures in Megacities and the design of composite structures. Keynote lectures were delivered by Professor Akira Hasegawa, Professor Akitoshi Mochizuki, Mr. Hiroshi Tanaka and Professor Askar Zhussupbekov.

The chairmen of the technical sessions were Prof. Talal Awwad (L.N. Gumilyov ENU, Damascus University), a member of Syrian Geotechnical Society and Prof. Sung-Woo Moon (Assistant Professor, Nazarbayev University), a member of Kazakhstan Geotechnical Society. Young geotechnical scientists from Japan and Kazakhstan introduced the oral presentations at the technical session.

The annual meeting of Italian Researchers in Geotechnics (IARG; https://www.iarg2018genova.com/) was held in Genova from July 4th to 6th, 2018, and it was hosted in the prestigious Villa Cambiaso in the University of Genova. The meeting was organised each year upon proposal of the Italian National Group of Geotechnics (GNIG; http://www.gnig.it/), which is composed of academic professors and researchers. The meeting was organised by the hosting institution and led by Riccardo Berardi, the chair of the Scientific and Organizing Committee.

The meeting was an effective and informal event for all people belonging to the Italian Academic Community to present on-going works and to share expertise and ideas. It is especially intended to give PhD students and young researchers an opportunity to present their work to distinguished audience. Four sessions were organised, each focusing on a specific topic, covering many relevant geotechnical-related research fields:

 Session 1: Soil and Rock Mechanics: experimental tests and modeling  Session 2: Geotechnical site and seismic characterization  Session 3: Geotechnical works  Session 4: Slope stability and Environmental Geotechnics

More than 80 contributions from all four sessions were presented, highlighting the importance of the Italian Geotechnical Community. A large variety of subjects were explored, as it summarised by the word-frequency map extracted from the titles of the contributions (see figure below). The 10 most frequent words are “analysis”, “model”, “seismic”, “soil”, “behavior”, “numeric”, “landslides”, “sand”, “study”, and “assessment” (representing about 17% of the total number of words). A very wide range of keywords were proposed, more than 350!

Together with the IARG event, a three-day PhD summer school on “Modelling Large Displacements in Geotechnical Engineering” was organised in Genova by Francesco Calvetti (http://www.gnig.it/summer- school/anno-2018/). The meeting also hosted the annual General Assembly of the GNIG and a very special social dinner in the exclusive location of Palazzo della Meridiana (http://www.palazzodellameridiana.it/)

The General Assembly has assigned the organisation of the 2019 meeting to Politecnico di Milano, which will be hosted in the Campus of Lecco (http://www.polo-lecco.polimi.it/) in the first week of July. The suggested topic is “The role of Geotechnical Engineering in Environmental Sustainability”.

Andrea Galli Politecnico di Milano ISSMGE Bulletin: Volume 12, Issue 4 Page 15 Hot news Engineering in Chalk Conference to be held in London in September 2018 www.chalk2018.org

The British Geotechnical Association (BGA), with support from the Engineering Group of the Geological Society (EGGS), is hosting a major international conference on Engineering in Chalk that will be held in at Imperial College, London on 17 and 18 September 2018.

Chalk underlies large parts of the UK and north-western Europe, and presents a diverse range of geotechnical challenges, that can affect building foundations, road and rail infrastructure, tunnels and other engineering projects. Over the past decades there has been considerable interest in characterising and understanding the engineering properties and behaviour of chalk. The last major conference on chalk was held almost 30 years ago in 1989 in Brighton. Chalk 2018 will bring together the knowledge and experience gained in the last three decades, and this conference presents a great opportunity to bring together research and case histories and to provide an up to date perspective on engineering in chalk. More than 90 papers have been accepted for the conference, and will be published in a Proceedings in September 2018.

The conference programme (https://www.chalk2018.org/programme ) comprises three Keynote Lectures and 58 other oral presentations (in two parallel sessions).

The Keynotes will be Professor Rory Mortimore on ‘Developing Ground Models for Chalk Engineering: Links across the Disciplines’; Dr Clive Edmonds on ‘Review of Collapse Events on Chalk since 2000 and the Opportunities for Improved Engineering Practice’; and Professor Richard Jardine on ‘Behaviour of Piles Driven in Chalk’.

Parallel sessions on Day 1 will cover Case Histories, Earthworks, Foundations & Piling and Geological Hazards. Highlights include presentations of the Andrew Lord Memorial Papers on HS1 earthworks, case histories from Crossrail, Tideway and the Lee Tunnel, and discussion of cliff stability problems in chalk.

Day 2 parallel sessions will cover Site Investigation, In-situ and Laboratory Testing, Future Engineering Issues, Offshore Engineering, Tunnelling and Water & the Environment. Highlights include the mechanical and hydraulic properties of chalk, discussion of rota-sonic drilling in chalk and a comparison of EPB and slurry TBMs for tunnelling in chalk.

On the third day two technical visits are available (numbers are limited): 1. Excursion to the chalk exposures of the Sussex Coast of southern England: Led by Professor Rory Mortimore. 2. Visit to chalk mine legacy sites in the Reading area of southern England: Led by Dr Clive Edmonds. This will involve a walk around Coley area, Reading in the morning to view evidence of past quarrying/mining and crown hole collapses. This will be followed by a visit to the Emmer Green chalk mine visit near Reading (this in an underground visit and requires climbing of ladders).

Registration is open via the Chalk 2018 website ( https://www.chalk2018.org/registration ). The delegate fees are below, and include for both days of the conference (Monday 17 and Tuesday 18 September 2018). Delegates will receive an electronic copy of the conference proceedings on a USB storage device. Technical visits on Wednesday 19 September can be booked, for which an extra fee applies.

Delegate rate £300 Discounted delegate rate for BGA Member £220 Student/Retired (BGA Member & Non-Member) £50 Technical Visit (details on programme page of Chalk 2018 website) £75 in addition to delegate fee ISSMGE Bulletin: Volume 12, Issue 4 Page 16 Hot news De Beer’s Award – Ir Flor De Cock

Late Professor E. De Beer’s friends and colleagues took the initiative in 1982 to publish a memorial volume at the occasion of his retirement. The proceeds of that publication were used to establish the “De Beer Fund” and enable the award of the “De Beer Prize” every four years.

Ir Huybrechts Noeil Head of Geotechnical Division Chairman of ISSMGE TC211 Ground Improvement ISSMGE Bulletin: Volume 12, Issue 4 Page 17 Obituary In Memoriam: Professor Iacint Manoliu (1934 – 2018), by TC306

Professor Iacint Manoliu passed away on June 12, 2018, at a hospital in Bucharest. He is survived by his twin sister Arina, his wife and companion (Sandra) of almost 60 years, his daughter (Mihaela), son (Costin) and grandchild (Victor). May they live a long life to remember him.

And how many remarkable things they have to remember!

The parents of Iacint, Alexandra and Ioan Manoliu, were professors at two of the most prestigious high schools in Bucharest. Iacint started playing sports early, together with his older sister Lia. At the beginning ping-pong on the dining table, then tennis at the Romanian Tennis Club in Bucharest. In 1948 he became the national tennis champion at the children’s category (under 15). Prior to becoming a construction engineer and teacher, Iacint Manoliu was for 12 years, between 1947 and 1959, sports journalist, editor of “Sportul Popular”, later called “Sportul”.

Iacint Manoliu obtained his Engineering (MSc) degree (1957) and PhD in Civil Engineering (1974) from the Technical University of Civil Engineering in Bucharest (UTCB). He started his academic career as a Teaching Assistant (1959–1966), then Assistant Professor (1966–1975), Associate Professor (1975–1982) and Full Professor, always at UTCB. He further served UTCB from the positions of Associate Dean (1972–1976) and Dean (1976–1984), Faculty of Civil, Industrial and Agricultural Buildings, Vice-Rector for Academic and International Affairs (1990–1996), Vice-Rector for International Affairs (1996–2000), and President of the Council for Cooperation and International Relations (2000–2011). ISSMGE Bulletin: Volume 12, Issue 4 Page 18 Obituary (Con’t) In Memoriam: Professor Iacint Manoliu (1934 – 2018)

Professor Manoliu was author and co-author of more than 100 published books, handbooks and papers in the field of soil mechanics and foundation engineering and in the field of engineering education. He was co- principal investigator in a research project carried out jointly by the Department of Civil Engineering, University of Texas at Austin and the Design and Research Institute for Oilfield Equipment, Bucharest, concerning pile foundations for offshore structures (1976–1986). Professor Manoliu supported numerous scientific, professional and international activities. He was Correspondent Member of the Romanian Academy of Technical Sciences (2005–2018), President of the Romanian Society for Soil Mechanics and Geotechnical Engineering (1996–2012), and Vice-President of the Union of Associations of Civil Engineers of Romania (UAICR, 1996–2018).

He served the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) in many capacities, promoting consistently education issues. He was member of TC 31 (Education in Geotechnical Engineering, 1993–2005) and TC 306 (Geo-engineering Education, 2009–2018), and Chairman of ECT 16 (European Technical Committee on Education & Training, 2007–2011). He chaired four international conferences:

 Danube-European Conference on Soil Mechanics and Foundation Engineering, Constantza, 1995;  First International Conference on Geotechnical Engineering Education and Training, Sinaia, 2000;  Second International Young Geotechnical Engineers’ Conference, Constantza, 2003;  First International Conference on Education and Training in Geo-engineering Sciences: Soil Mechanics, Geotechnical Engineering, Engineering Geology and Rock Mechanics, Constantza, 2008.

The technical committee for Geo-engineering Education, TC306, is grateful to Professor Manoliu for conceiving and organizing the first two international conferences on Geo-education (2000, 2008) and for recording their history and successful continuation in a paper presented at the 2016 conference in Belo Horizonte, Brazil, which is available through ISSMGE’s online library.

In addition, Professor Manoliu served the European Society for Engineering Education (SEFI) as member of the Administrative Council (1998–2006), the European Association of Civil Engineering Faculties (AECEF) as member of the Executive Board (1998–2006), the European Council of Civil Engineers (ECCE) as Vice- president (1999–2005) and Chairman of the Standing Committee on Education & Training (2003–2016), and the European Civil Engineering Education and Training (EUCEET) Association as Secretary General (2008- 2018). Professor Manoliu will be remembered by a significant number of civil engineers, many of whom geotechnical engineers, for his dedication to coordinating various network projects, many funded by the European Union, which provided opportunities for large-scale teamwork on civil engineering education.

While he never abandoned international cooperation efforts, in later years he found time to return to journalism, this time writing about his sister Lia Manoliu (1932– 1998), the first track and field athlete to compete at six Olympics (1952–1972). Lia Manoliu won two bronze medals (1960: Rome, 1964: Tokyo) and one gold (1968: Mexico City) in discus throw. Being in the USA on a Fulbright scholarship, Iacint managed to travel to Mexico City, be at the Olympic stadium and celebrate the gold medal with Lia.

Professor Iacint Manoliu lived a full life and celebrated many accomplishments Manoliu, I. 2016. Letters and happy moments within his own family, his geotechnical engineering family from Lia, Vremea and his civil engineering family. He will be remembered by all with love, gratitude Editions, Bucharest. and respect.

The Romanian Society of Geotechnical and Foundation Engineering (RoSGFE) is announcing with the deepest regrets that Professor Iacint Manoliu passed away on the 12th of June, 2018, at the age of 84 years. This was a difficult moment for our society.

Professor Manoliu was a founding father of the RiSGFE and will remain in the heart of this professional family. In this regard, we present a chronological synthesis of his activity over 60 years, on a national and international level.

Iacint Manoliu was an Emeritus Professor at the Technical University of Civil Engineering Bucharest. He was born on April 5, 1934 in Botosani. He attended a high school in Bucharest, graduated in 1952, and the Faculty of Civil and Industrial Buildings of the Bucharest Institute of Civil Engineering (ICB), graduating in 1957. He became a member of the Department of Geotechnics and Foundation Engineering of ICB in February 1959, occupying successively the positions of Head of Laboratory, Assistant, Lecturer (1975), Professor (1982), Consultant Professor (2004) and Emeritus Professor (2012).

In 1974 he obtained his PhD title, after presenting at ICB the thesis entitled "Behavior of piles subjected to transverse loads". He was the main researcher in a joint venture project of the Department of Civil Engineering at the University of Texas at Austin and a design institute (IPCUP) from Bucharest on offshore platform piles, between 1976 and 1986.

He was the author and co-author of more than 100 books, textbooks, communications, papers and prescriptions in the field of geotechnical engineering and higher technical education.

Since 2004 he was a correspondent member of the Academy of Technical Sciences in Romania.

In 2008, the "Gheorghe Asachi" Technical University Iasi awarded him the title of Doctor Honoris Causa.

He has held leading positions at the Institute of Civil Engineering Bucharest (from 1995 Technical University of Civil Engineering in Bucharest): Vice- Dean (1972-1976) and dean (1976-1984) at the Faculty of Civil, Industrial and Agricultural Construction, Vice-Rector (1990-2000) and President of the Council for Cooperation and International Relations (2000-2011).

He was a founding member of the Romanian Society for Geotechnical and Foundation Engineering and served several roles in the society as vice-president between 1990-1996 and President of the society between 1996- 2012. Since 2012 he was the Honorary President of the RoSGFE. He initiated the publication of the Romanian Journal of Geotechnical and Foundation Engineering, since 2004.

Between 2007-2011, Professor Manoliu chaired the European Technical Committee 31 "Education and Training in Geotechnical Engineering" of the ISSMGE.

Since 1990, Professor Manoliu has initiated and coordinated numerous projects in the field of higher education funded by the European Commission, including the EUCEET Thematic Networks (European Civil Engineering Education and Training) developed between 1998-2010. Since 2008 he was Secretary General of the EUCEET Association.

ISSMGE Bulletin: Volume 12, Issue 4 Page 20 Obituary (Con’t) In Memoriam: Professor Iacint Manoliu (1934 – 2018), by Romanian Society of Geotechnical and Foundation Engineering (RoSGFE)

He has worked as a European expert in the Tuning-Latin America (2006-2012), Tuning-Georgia (2008-2009) and Tuning-Russia (2011-2013) projects.

Since 2008 he was an international expert for C.T.I. (Commission des Titres d'Ingénieurs, France).

Between 1994-2005 he was Vice-President of E.C.C.E. (European Council of Civil Engineers), and since 2003 has lead the permanent Education & Training Working Group of E.C.C.E.

He was a founding member of E.N.A.E.E. (European Network for Accreditation in Engineering Education) and since 2008 was a representative of E.N.A.E.E. of ARACIS (Romanian Agency for Quality Assurance in Higher Education).

We believe that the living testimonies of his work dedicated to the field of Geotechnical Engineering, namely his books, researches and projects, all of which serve as current technical norms that govern the prescriptions in Romania, bear his mark, along with the theories, the methods of calculation and the newly introduced and promoted in our country, and most importantly with the specialists formed under his guidance as a Professor in TUCEB, thus creating the "geotechnical engineer".

Professor Manoliu has been and has remained our “open door” to Europe and the world, a valid unlimited passport. The name of Manoliu in the international geotechnical community is identified with Romania.

The de facto founder of the RoSGFE, leading its destiny permanently, our Honorary President, will remain forever for us and will pass further to future generations a model of modesty, fairness, professionalism and patriotism, as a complete intellectual and lover of fine arts, and above all a MAN.

ISSMGE Bulletin: Volume 12, Issue 4 Page 21 Obituary (Con’t) In Memoriam: Professor Iacint Manoliu (1934 – 2018), by Romanian Society of Geotechnical and Foundation Engineering (RoSGFE)

We are grateful for Professor Iacint Manoliu’s contribution in our lives and we ensure that he will never be forgotten.

We sincerely appreciate the international geotechnical engineering community for the emotional messages sent.

China – Europe Conference on Geotechnical Engineering was held in Vienna, Austria, from 13th –16th August 2018. The conference was organised at the BOKU University, Vienna and this was a unique conference that is intended to bring together researchers and practitioners from China, Europe and all over the world to share recent advances in geotechnical engineering. There were about 350 participants from 30 countries from the six continents. 420 papers were published by Springer series, and there were 300 presentations in 13 parallel sessions and special sessions.

The opening ceremony was held on 13th August. The session chairmen were: Prof. Wei Wu and Prof. Hai-sui Yu. The plenary lectures were presented by different universities and countries from China, Poland, Spain, Italy and the U. K. I attended the presentations by Prof. Eduardo Alonso - Tunnelling in Urban Environments. Protecting Sensitive Buildings; Prof. Michele Jamiolkowski - Zelazny Most Tailings Disposal Geotechnical Challenges; Prof. Charles W. W. Ng - Bioengineering for Slope Stabilisation Using Plants: Hydrological and Mechanical Effects. The lectures were highly enlightening.

There was also a special session called the “Workshop in honor of Gudehus 80th birthday. The sessions covered all the topics that are important for geotechnical engineering directions.

My presentation was at the session Geohazards – risk assessment, mitigation and prevention. The chairmen were Dr Xueyu Geng (Warwick, UK) and Dr Stefano Utili (Newcastle, UK). There was discussion about the use of different methods to assess natural hazards.

The closing ceremony was on 16th August, which was held in the BOKU university garden, where Prof. Wei Wu thanked all of the participants to attend the conference in Vienna.

The lectures, presentations, papers were of high quality. I attended a lot of presentation. Now I know more interesting people and I have an invitation from other conferences which is a great opportunity for my future research career. Overall, the conference was really enlightening, informative and very well organised.

The International symposium on Cone Penetration Testing was a conference solely focused on CPT testing, and thus attracted the most well-renowned CPT experts; academics and industry professionals alike. Having a very focused theme, the articles and presentations were of extra-ordinary quality, and the opportunities to network were great. The 4th conference of this series was held in Delft on the 21st and 22nd of June.

There were three different keynote lectures: the first by Dr. Mark Randolph on the use of penetrometers, the second by Dr. Ross Boulanger on the interpretation of thin layers from CPT data and their consequences for liquefaction potential, and the third by Dr. Kenneth Gavin on the design of shallow and deep foundations using CPT data. There were two discussion sessions: the first led by Dr. Peter Robertson which mostly revolved around strain rate effects and interpretation of thin layers, and the second led by Dr. Paul Mayne which mostly focused on interpretation of soil profiles. There were eight different sessions with presentations made on published articles. Additionally, the indoor exhibition by many leading companies in the Europe had different kinds of cones, sensors, sampling and testing equipment etc on exhibit and the outdoor exhibit had a couple of cone rigs on exhibit, which I saw for the first time.

I was lucky enough to have an article published in the conference. Only a select top few of all the published articles are presented, and I was also one of the selected people. On the first day of the conference, I got to present my work, and was introduced by Dr. Peter Robertson who was the session chair. It was the highlight of the conference for me to be introduced by Dr. Peter Robertson, whose work I really admire.

The CPT’18- International Symposium on Cone Penetration Testing was announced and organized by the Technical Committee TC102 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and hosted by Delft University of Technology. The previous symposiums were successfully organized in Sweden (1995), and USA (2010, 2014).

The conference started with the distinguished keynote lecture by Professor Mark Randolph which was about the penetrometer equipment and testing techniques for offshore designs. Professor Randolph is a well- known figure in industry and academia and it was a unique opportunity to attend one of his lectures. The keynote lecture was followed by three sessions chaired by the experts in their area. The discussion breaks in between sessions were more than educational and allowed attendees to participate. The poster presentations were made at the end of the first day, in which I had also chance to present my work and take advices on the follow-up future research ideas. The second day of conference started with the keynote lecture of Ross Boulanger which was about the inverse filtering procedure to correct cone penetration data for thin layers. Another keynote lecture was by Kenneth Gavin which was about the use of CPT for the design of shallow and deep foundations on sand. The whole day consisted of eight different sessions hosting paper presentations.

In general attending one of the premiere events in geotechnical engineering, CPT’18 allowed me to meet, network and learn from the world’s expert professional academics, researchers, consultants, practitioners etc. I also believe that participating this conference broadened my horizons in the field of geotechnical engineering by sharing and following the contemporary/state-of-art research and practices.

From 3rd to 5th August 2018, the 7th International Conference on Unsaturated Soils (UNSAT 2018) was hosted at the Hong Kong University of Science and Technology (HKUST). UNSAT 2018 hosted the 2nd Blight lecture, presented by Prof. D. Fredlund. The presentation emphasised the importance of the soil water retention curve (SWRC) and identified it as being the key to implementing unsaturated soil mechanics in geotechnical engineering practice. Prof. Fredlund illustrated how volumetric measurements taken during a drying or wetting cycle can be used in conjunction with a conventional gravimetric moisture content versus suction relationship to provide a more complete understanding of unsaturated soil behaviour. In addition to the Blight lecture, several keynote lectures were expertly delivered by world renown researchers, each providing valuable insight into a specific aspect of the field.

The remainder of the conference was carried out in two parallel sessions where each presenter was allocated a five-minute presentation. Despite the time constraint, the presentations given were succinct and all researchers managed to convey key aspects of their work within the short time frame. The fast-paced nature of this arrangement allowed attendees to maximise their intake during the three days of the conference. Delegates were also given a tour of the geotechnical laboratory at HKUST. Being able to witness the inner workings of one of the world’s top unsaturated soils laboratories was an amazing e experience.

Attending UNSAT 2018 allowed me to be exposed to the state-of-the art in unsaturated soils research. The opportunity to meet and discuss ideas with the top researchers in the field was insightful, inspiring and will undoubtedly benefit the quality of my doctoral thesis, as well as any research conducted thereafter. I am extremely grateful to the financial assistance provided by the ISSMGE Foundation, without which this experience would not have been possible.

50 years in the forefront of innovated CPT technology In 1968 Arie Pieter van den Berg founded A.P. van den Berg in Heerenveen which focused on the design and production of machines and equipment for Cone Penetration Testing (CPT). This by origin Dutch soil investigation method was still in its infancy and Arie van den Berg assumed the role of ambassador for this technology. In a relatively short time, he contributed to a worldwide acceptance of the method and the associated CPT technology and managed to build a strong international reputation for his company. In 2018, the year that the company celebrates its 50th anniversary, this reputation still stands. The drive for innovation, the high product quality and in-house engineering and production are main success factors behind their leading market position. The introduction of the very compact and fully automated SingleTwist™-system, attests the focus on innovation once again.

ST-rods: the (un)folding CPT string The basis of the SingleTwist™-system consists of the (un)folding ST-rods. These rods can be in one of just two states, twisted or untwisted, and it takes very little to transform them from one state to another. Untwisted, the ST-rods behave a bit like a pearl necklace and can be easily folded onto a reel. Once twisted, the rods form a solid CPT string with a push/pull/buckle performance equal to a string of standard CPT rods. Because the rods have a self-seeking bayonet thread they close effortlessly and require just a final, short, single twist to become firmly interlocked, hence the name SingleTwist-rods. Having rods with this patented design, the transformation process during CPT pushing as well as pulling is like a natural flow and done almost entirely mechanically, making it very robust indeed.

All it takes to put together an automated CPT system, i.e. one that performs a full CPT and a subsequent complete reel-in of the string on a single operator command, is a Folder, a Twister and a Sprocket (a wheel to connect the two). This very compact SingleTwist™ system can be combined with virtually any A.P. van den Berg pusher, including onshore COSON penetrometers and ROSON seabed systems. Needless to say that, since the ST-rods come fitted with an Icone cable, users enjoy the full bandwidth of A.P. van den Berg’s digital bus and become compatible with all Icone sizes and all available click-on modules: Seismic, Conductivity, Magneto & Vane.

COSON-ST: fast & hands-free CPT machine for onshore soil investigations The COSON-ST builds on the unrivalled track record of the Icone technologies and large range of CPT rigs including the Track-Truck®, an A.P. van den Berg invention. Through the years each design is continuously improved, i.a. resulting in developments that enhance the operator’s working conditions. One example is the COSON double acting penetrometer for continuous pushing in combination with the automatic rod screwing device, that will fasten the rods automatically once the rod is placed in this device. This combination reduces handling requirements for the operator. Hence, less physical strain. The remaining challenge has been to create a fast CPT system that does not require any manpower at all, has a compact design to fit a CPT cabin and is compatible with all Icone click-on modules. The COSON-ST is the answer.

By integrating the patented SingleTwist™-system into a CPT cabin with the COSON penetrometer, a fast CPT machine for hands-free operations is created. Several folder sizes are available holding up to 70 m of CPT string. The COSON-ST does not require any manpower during the push/pull cycle of a CPT. ISSMGE Bulletin: Volume 12, Issue 4 Page 42 News from Corporate Associates (Con’t) A. P. van den Berg

The operator only has to provide the start/stop signals. The pushing process is continuous, generally resulting in shorter pushing times, increased penetration depths and no dissipation effects associated with a single clamp’s discontinuous pushing process. The pulling process with the COSON-ST is also 20% faster than with a single clamp system, so the total CPT cycle time is reduced considerably.

ROSON-ST: up to 50 m CPT with the compact & easy to handle seabed CPT system The ROSON-ST builds on the unrivalled track record of the existing ROSON and Icone technologies. The digital Icone has been around for almost 15 years and the ROSON technology has proven itself for robustness, reliability and CPT quality over the last 35 years. The remaining challenge has been to eliminate the need to support the CPT string, particularly with ever increasing CPT depths. This external string support makes a ROSON system heavier, more difficult to handle and time consuming to set up. Compact solutions available today introduce shortcomings of their own, concerning achievable penetration depth, data reliability, cone sizes to choose from and increased wear and tear. The ROSON-ST, the integration of the patented SingleTwist™-system into the proven ROSON system, is the answer to these issues.

Through the compact design, the ROSON-ST is easy to handle from most vessels. It can be deployed for projects from shallow to ultra-deep water. Both a 1,500 m version as well as a deep water version for water depths up to 4,000 m are available. The ROSON-ST does not require any exterior CPT string support, assuring fast deployment and high productivity. The use of the patented ST-rods ensures the straight push that may be expected from a CPT system. It is suitable for 50 m penetration. The standard configuration with a 10 tons pushing force will be more than enough for the majority of your projects, but a 20 tons version is also available.
