摘　　要：随着我国山区公路建设的加快,许多公路的修建无法避免会引起边坡灾害,本文以通江县两河口乡沙窝寺滑坡工程为例,通过分析边坡变形历史、滑坡体边界特征及坡体稳定性,得出滑坡体处于缓慢蠕变阶段,属于中型土质滑坡,在遭遇20年一遇强降雨情况下,坡体处于不稳定状态,有可能再次发生滑动。根据滑坡体分布范围、危险区范围、滑坡性质,提出采用桩板墙与后缘裂缝填埋并设置排水沟的治理措施,可以很好地抑制边坡变形,为此类滑坡的治理提供参考,为公路边坡的治理提供示范作用。With the acceleration of mountain highway, it is unavoidable to induce landslide disasters in many road constructions. Take Shawosi landslide as an example, this paper analyzes the history of slope deformation, the characteristics of the landslide boundary and the slope body stability, the conclusion is that the landslide body is in a slow creep stage and belongs to a medium-sized landslide. In the case of 20-year severe rainfall, the slope is in an unstable state and may slip again. According to the distribution range of the landslide bodies, the dangerous area range and the nature of the landslide, the treatment measures of sheet-pile wall and back edge crack landfill with drainage ditch is are proposed for control the slope deformation, which can provide example for the treatment of highway slopes.
