In this paper, a risk assessment method based on limit equilibrium method is proposed. It has been used to estimate the risk of forming wedge body in a landslide in southwest of China. According to the monitoring data and the result of stability analysis using limit equilibrium method and three-dimensional finite element method, we find that due to the rising of water table, the landslide tends to limit-equilibrium state. The displacement under normal condition is consistency with that of monitoring. It is possible to slide under dynamic condition, but the landslide cannot block the river totally. The research achievements have been used to make contingency planning and are of great significance.
