Probabilistic Slope Stability Analyses—A Case Study
In this paper, the stability of a 40 m high cut slope was analyzed using both deterministic and probabilistic approach. According to the subsurface investigation, sand and clay layers existed at the site, however, the thickness of the layers varied across 1.2 km of the slope. The most critical thickness and order of layers were identified to develop representative cross section. The groundwater effect along with variations in soil shear strength properties were considered in the analysis. The results of in-situ tests and laboratory tests were used to extract soil properties. Consequently, from deterministic analysis, the safety factor at different ground water conditions in the representative cross section was adequate. However, the probability of failure was high and drainage trenches along each of the slope benches were installed to bring the ground water level down permanently. The probabilistic analysis provides an insight to slope design and ground water level adjustments to mitigate the associated risk when there are uncertainties in subsurface investigation.
