Thesis (M.Sc.)--The University of Manitoba (Canada), 2002.

In 1999, after a period of extensive rainfall, two slope failures developed within the right-of-way of Provincial Road 259 near Virden, Manitoba. It is postulated that extensive rainfall events in 1999 caused dissipation of soil suction that reduced total shear strength triggering failure. Following the slides, a research project was initiated between the Geotechnical Group at the University of Manitoba and the Manitoba Department of Highways and Transportation to determine the cause of failure. A detailed research program that included the assessment of the geology, geomorphology, site conditions, field conditions, laboratory testing, and numerical modelling was undertaken to quantitatively identify the cause of failure.

520 $a A transient coupled seepage analysis and slope stability computer model was constructed to analyze the impact and contribution of matric suction and the weather conditions on slope stability. The Seep/W and Slope/W computer programs from GeoSlope Int. (Calgary, Alberta) were used in the analysis. (Abstract shortened by UMI.)
