FOR YEAR ENDING JUNE 1966

INCLUDING MEMBERSHIP LIST OF THE CANADIAN SECTION

Prepared by ANALYZED

Technical Memorandum No. 89

OTTAWA September 1966 (i)

FOREWORD

An Annual Report of the Canadian Section is not issued during the years of the International Conferences and this Report is therefore a summary of the activities of Canadian members of the International Society of Soil Mechanic s and Foundation Engineering for the period June 1964 to June 1966.

It is published for the purpose of keeping Canadians informed of those soil mechanics investigations which are being conducted in their own country. In this way, it will assist in overcoming the natural handicap offered by the widespread geographical distribution of soil mechanics work in Canada.

The report includes a list of publications by members of the Canadian Section. In addition, it includes a list of known thesis topics presently under study and a list of suggested research projects. It is hoped that these lists will develop into useful sources of information. A special effort has been made to reduce reports on routine work. It is probable, however, that some of the work noted was of a routine nature but was considered worth including because of possible general interest. Brevity in reporting the work has been attempted.

Anderson, C. E.

Continuation of the lime stabilization research programme.

Differential thermal analyses are run on selected samples to evaluate chemical changes.

In conjunction with foundation studies for proposed dam sites in northern Manitoba, continuous cores of permafrost-affected soils were collected, photographed and classified as to type of permafrost and soils properties.

The permafrost characteristics are being related to such factors as location, vegetal cover and climate.

Influence of pseudo-montmorillonite present in Leda clay on the Atterberg limits, permeability and remoulded consolidation charactz ristics of Leda clay. The clays are homoionized in different monovalent cations to alter the amount of interlayer water between the montmorillonite sheets. Division of Building Re search, National Research Council

Soil Moisture and Volume Change

Continued with the' correlation between climate, soil m-oisture and soil volume changes at sites at Winnipeg, Regina, Eston and Melfort in western Canada. Developmeilt of equipment and techniques for field calibration of nuclear moisture and density probes.

Soil with High Sulphate Content

Mapping of potential sulphate hazard to concrete in soils of an area of central Saskatchewan was carried out. A number of concrete structures of various ages and compositions were examined in areas of soils with high sulphate content.

Permafrost Distribution

Field reconnaissance of distribution of permafrost was conducted in northern British Columbia and the Yukon was conducted in October 1964, followed by a similar survey of northern Ontario and eastern Manitoba in 1965. Ground temperature measurements were continued in the Inuvik vicinity and at Thompson, Manitoba.

Frost Action

The pressures exerted by the growth of ice lenses in various media are being measured in the laboratory. Materials used include sorted glass beads, brick, mortar, sandstone, and natural soils.

A new technique for investigation of frost susceptibility based on the intrusion of air into soil, which is analogous to the freezing of soil, is being pursued.

Mu s ke g Studies

Some tests have been conducted on frozen peat samples to give an indication of the rheological properties. Apparatus has been constructed to conduct plate loading tests on peat. Federal Department of Transport

A research programme has been undertaken aimed at the determination of the dynamic moduli of elasticity in situ. The method employed was that of propagation and separate recording of compression and shear waves. By recourse to the classical theory of elasticity, the dynamic modulus of elasticity, shear modulus and Poisson's ratio has been computed.

Laboratory investigations are being conducted, on a continuing basis, into the residual strength of clay soils, in an attempt to account for the discrepancy between the field behaviour and predictions based on laboratory shear strength.

Work was continued on the measurement of soil moisture tension, diffusivity and conductivity, and on the use of these data in computing infiltration and redistribution of moisture in soils using finite difference methods for solving the flow equation. Special emphasis was given during the year to infiltration into layered soils and to hysteresis effects (using drying scanning curves) during redistribution of moisture following infiltration. A computer programme was written also to take into account hysteresis in moisture tension during wetting as well as during drying, as suming that the independent domain theory was appl icable.

Thomson, S.

Frost heaving in railroad subgrades - this investigation was of a practical nature and open system freezing tests indicated that the location of the water table and the soil type were the main factors contributing to heaving. The addition of various salts decreased the amount of heave.
