(i) FOREWORD

An Annual Report of the Canadian Section is is sued each year and this Report is, therefore, a summary of the activities of Canadian members of the International Society for Soil Mechanics and Foundation Engineering for the period June 1966 to June 1967.

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.

Particle -size Analysis of Soils

Four mechanical shakers: Eberbach, thumbler, wrist-action and Bouyoucos with periods of agitation of 15, 30 and 60 minutes for the latter and of 2, 4 and 8 hours for the others, were compared for particle-size distribution analyses of seven Quebec soils. The percentages of clay, silt and sand were used to evaluate the

individual treatments. The four shakers were equally efficient in dispersing soils even for the shortest shaking periods.

Canadian National Railways

Continuing study of reduction of frost heaving of railway track with granular NaCl. Analysis of extensive track tests shows economical results in first winter. Techniques and longer -term results are being studied.

Clark, J. 1.

A study of the elastic properties of a dense coarse gravel has been completed. The techniques included a seismic survey to measure velocities of shear waves and compression waves which were distinguished on the basis of amplitude and plate bearing tests in a horizontal direction. The gravel bed was examined in detail to determine if a relationship exists between anisotropy measured and preferred particle orientation. The gravel deposit serves to support a 600 ft restaurant tower which was instrumented in order that elastic deflection could be recorded as construction proceeded. These are correlated with properties measured prior to construction. A technical paper is being prepared.

The loss of strength associated with stress relief was investigated on undisturbed block samples from Larribto n GS

The strength of the soil was then measured under Ko stresses and under isotropic stresses after removal of initial stresses. The programme is to be continued in 1968.

A preliminary study of the use of blending fine grained soils with free draining soils to produce suitable earth darn core

materials was made. The fine grained materials consisted of clay, silt and peat.

Measurements of liquid permeability in partially saturated cable backfill soils were made using the pressure outflow method. Also, measurements of vapour permeability were made in the same soils. These data were used in analytical studies of the

migration of moisture due to the r rna l gradients induced by high-voltage underground cables.

(15)

-The test results were analyzed to show that the compressibility of partially saturated soils was not a unique function of effective stresses. Instead, it was found to be some function of the total stresses and suction. The mechanism of swelling and collapse on wetting was explained in terms of interparticle stresses.

Finally, an incremental stress-strain theory to predict the volume changes under isotropic and anisotropic stresses was proposed and experimentally verified.

Abutment response to dynamic loads, discontinuity surfaces or "shocks" causing abrupt changes in stresses and velocities adjacent to a moving retaining structure.

Meyerhof, G. G.

Research on the strength of corrugated steel arches has been carried out in compacted sand back fill. Arches of various sizes were tested under fill having various heights of cover, loaded uniformly and by concentrated loads applied at the soil surface. The pres su re s, deformations, strain s in the arch and ultimate load of the soil-structure systems were determined by comparison with an extended theoretical analysis. (Ph. D. Thesis by L. D. Baikie).

A study is underway on the causes of apparent subsoil movements exhibited in a large number of slope indicator records from bentonitic shales with numerous thin seams of bentonite. Plots of these apparent movements, which often change direction, do not conform with scatter and pattern expected from probable and systematic errors due to inaccuracies of the instruments used.
