摘　　要：本研究在论述了西马峪滑坡侵蚀体的形成、岩土体特征、滑坡滑动和变形破坏特征的基础上,首先定性分析、定量计算评价了西马峪滑坡侵蚀的稳定性,结果表明,两马峪滑坡侵蚀体处于临界一不稳定状态,最后对西马峪滑坡侵蚀体潜在侵蚀量进行了评估,提出了应当采取工程治理措施,防止滑坡侵蚀灾害进一步加剧,制止水土流失的发生。Based on the study on the forming processes of landslide erosion body, characteristic of the rock-soil body, and characteristic of sliding and distorted breakage of the landslide, the stability of the Ximayu landslide erosion was evaluated by both qualitative analysis and quantitative computation in this paper. Results showed that the Ximayu landslide erosion body was under the critical to instable state.And a project controlling measure was proposed to prevent erosion development and hold out loss of soil and water after the amount of potential soil erosion was evaluated in the Ximayu landslide erosion body.
