The stability conditions after the instability of sliding is a concern issue; it is the significant foundation to conduct objective assessment for selecting engineering management measures. According to the geological background and geological exploration data, some representative sections as well as their stability conditions were studied and analyzed based on limit equilibrium method for rigid block and three-dimensional nonlinear FEM in this paper. The impacts on the slop stability by different depths of the transient saturated zone caused by groundwater as well as rainfall infiltration were taken into consideration during the calculation analysis. It is indicated by the results that the impacts on the landslide mass displacement by rainfall have distinguish spatial properties; the impacts on vertical displacement is bigger than that of the horizontal direction; the obvious impacting zone is located in the little backer anterior border area of the landslide mass. The calculation results can provide important references for the control and reinforcement of the landslide mass as well as the prevention of landslide hazard during the later engineering construction activities.
