%X The Enziping 2<sup>#</sup> landslide is a typical bedrock bedding landslide located at about 8.6 km   downstream of Baihetan Hydropower Station. We analyzed the stability of the landslide qualitatively by means of physical simulation tests, and meanwhile discussed the laws of displacement, stress, and deformation changes under different working conditions via numerical simulation based on engineering investigation data. Results suggest that the combination of physical simulation and numerical simulation is an effective approach to analyzing the causes of landslide formation. The displacement of landslide increased gradually from bedrock to sliding body, with the maximum displacement reaching 185 cm under flood level condition, and the deformation mainly occurring in sliding body. The maximum tensile stress was found at the underwater accumulation of the landslide. It natural state, the landslide was stable, and the safety coefficient was 1.065 6; under flood level condition, the safety factor of landslide reduced to 0.76 when the landslide tended to be unstable and the front edge of the slide was likely to suffer from local buckling down.
