Finite element method,slope stability,factor of safety,two-layer undrained slope,failure mechanisms of slopes

The note presents results of stability analyses of two-layer undrained slopes by the finite element method. The study focuses on the circumstances under which either deep or shallow failure mechanisms occur, as a function of the strength ratio of the layers, the slope angle and foundation depth ratio. Improved knowledge of the location of the critical failure mechanism(s) in two-layer systems, will give engineers better insight into where to focus their attention in terms or remediation or reinforcement to preserve stability.
