中文摘要	A direct constraint procedure was used to model the discontinuous mechanical behavior (such as sliding and disjointing) of faults and weak interlays in steep slopes to evaluate the safety of such slopes. The direct constraint procedure is the most robust procedure for contact mechanics. The elasto-plastic FEM was used to model the contact characteristics between the faults and the rock mass to analyze the excavation process for the Pengshui hydropower station. The results show that the magnitude and distribution of the deformation, the stresses and the plastic yield zones are all greatly increased by the sliding and disjoining, which increase the probability of landslides affecting the slope safety.
