Slope stability is the geotechnical analysis of a soil covered hillslope and its potential to undergo mass wasting. Slope stability is a focus of soil mechanics. It is the product of the balance between shear stress and shear strength. A previously stable slope may be initially affected by preparatory factors, making the slope conditionally unstable. Triggering factors such as climatic events can then make a slope actively unstable, leading to mass movements. Mass movements can be caused by increases in shear stress, such as loading, lateral pressure or transient forces. Alternatively, shear strength may be decreased by weathering, changes in pore-water pressure or organic material.
Slope stability analysis
Different methods are used to calculate the factor of safety of a potential slip surface depending on the geometry of the slip surface. For the simplified model of a circular surface, the Bishop’s Simplified Solution may be used.
