Characterization of a landslide-prone glaciolacustrine clay from the Thompson River Valley near Ashcroft, British ColumbiaDownload
Several large landslides have occurred in the Thompson River Valley near Ashcroft, British Columbia. The movement of these landslides have presented challenges for the operation of the two national railways that traverse this valley. The landslides are multiple retrogressive, translational,...
Detection of shear zones in a natural clay slope using the cone penetration test and continuous dynamic samplingDownload
Abstract: The detection of shear zones along which a mass of soil is moving is essential for understanding the state of stability of natural slopes. Weaker zones in clay soils can be identified from low values of cone penetration test (CPT) tip resistance measured during penetration. This paper...
Abstract: Twenty topples are described from Rock Glacier Site, 2 km north of the summit of the Highwood Pass in the Front Ranges of the Rocky Mountains in Alberta. In situ field testing and laboratory tests indicated that the external force driving the toppling process is frost action within a...
Mining methods have changed and grown to fulfill extractive demands. Heavy machinery is used to extract overburden in open pit and open cast mines and to create waste dumps prone to slope stability issues. As the heaviest equipment operating on dump locations, mine haul trucks require a safe,...
Abstract: The relationship between the shapes of the yield surface and the undrained effective stress path (UESP) of loose sand is investigated for triaxial loading conditions. It is shown that the UESP can be used in the construction of capped yield surfaces for sands. The stress ratio M-p...
