AbstractWenchuan earthquak induced a large number of mountain hazards. Through the survey found that manual excavation slopes tend to become concentrated area of mountain disaster, it's indicate that the effect of excavation damage on the slope deformation and failure under seismic load is very obvious. Soil slope deformation as one types of mountain hazards induced by Wenchuan earthquake, and it's also seriously affected by excavation damage. In this paper, as Shui Caoping landslide for example, using the finite element method to simulate the landslide and analysis the overall stability and the local deformation and failure of slope affected by the excavation damage. Analysis shows that the local damage is significantly induced by excavation, and resulting in vertical stress and plastic strain increased in the local of slope near the excavation face. While excavating also has the role of unloading. The results basic agreement with the characteristics of the slope deformation and failure induced by Wenchuan earthquake.
