Stability analysis of layered slopes in unsaturated soils
文献摘要：
This study presents stability analyses of layered soil slopes in unsaturated conditions and uses a limit equilibrium method to determine the factor of safety involving suction stress of unsaturated soil.One-dimensional steady infiltration and evaporation conditions are considered in the stability analyses.An example of a two-layered slope in clay and silt is selected to verify the used method by comparing with the results of other methods.Parametric analyses are conducted to explore the influences of the matric suction on the stability of layered soil slopes.The obtained results show that larger suction stress provided in unsaturated clay dominates the stability of the layered slopes.Therefore,the location and thickness of the clay layer have significant influences on slope stability.As the water level decreases,the factor of safety reduces and then increases gradually in most cases.Infiltration/evaporation can obviously affect the stability of unsaturated layered slopes,but their influences depend on the soil property and thickness of the lower soil layer.
