摘要: abstract:A mesh based partition of unity method, known as the manifold method, is used in simulating the evolution of a slope failure. The problem configuration consists of a simple slope that has pre-existing tensile cracks along its crest. The slope failure is triggered by rainfall which raises water pressure in the crack. As the
tensile stress around the crack tip increases, an existing crack grows and a failure surface is eventually developed. The maximum stress criterion is adopted in determining the crack growth and growth direction. After a failure surface is formed, the unstable soil mass, bounded by the failure surface, slides down the slope. This sliding process is also modeled.
