Engineers in geotechnical practice work on increasingly complex problems with increasingly powerful numerical tools. Effective solutions to design problems need good information about the site and parameters (or functions) ...

A major experiment - the tunnel sealing experiment, related to the disposal of heat generating radioactive wastes in geological formations and supported by government organizations from Japan, France, U.S.A., and Canada, ...

The paper proposes a new elastic-plastic framework for unsaturated, high-plasticity, clayey soils and sand-clay mixtures. The framework considers possible coupling of stress- and suction-induced hardening, leading to a ...

Water-retention dykes at Seven Sisters Generating Station in Manitoba have experienced irregular instabilities since they were heightened in the late 1940s. An investigation was undertaken to compare three locations at the ...

Two large-scale sealing experiments were conducted at Atomic Energy of Canada Limited's Underground Research Laboratory at Lac du Bonnet, Manitoba. The rate of water uptake in densely compacted sand-clay buffer materials ...

Quantitative application of elastoplastic theory to the yielding behaviour of natural soils has always been uncertain. Part of the reason is that the theory was developed for reconstituted materials with isotropic structure, ...

This paper models consolidation of the foundation soils under a test embankment at the new Chek Lap Kok International Airport in Hong Kong. The modelling used a simplified finite element method and material parameters ...

Limit states design methods and engineering judgement have been used to assess buoyancy issues for remediation of the 85 year old Shoal Lake Aqueduct in Manitoba. The study demonstrates how these methods can be applied to ...

The Cam-Clay model for isothermal mechanical behaviour of clays has been extended to take account of the effects of temperature on stress-strain behaviour. The assumptions used in constructing the new model are based on ...

In 1999, after a period of extensive rainfall, two shallow slope failures developed in the right-of-way of Provincial Road 259 near Virden, Manitoba. The rainfall caused dissipation of soil suction in the near-surface soil, ...
