摘　　要：老挝川圹省某电厂位于山前坡积地带,地形起伏很大,且地形破碎,地层以膨胀土和泥岩为主,按设计标高进行场地平整后,在厂址周边将形成人工膨胀土高边坡。由于边坡的稳定直接关系到电厂的安全,一旦破坏后果较为严重,因此,文章选取典型边坡,通过对可能产生的潜在边坡破坏进行平面滑动和圆弧滑动稳定性评价,评价结果为该电厂高边坡设计与治理提供了重要依据。A power plant in Xieng Khuang Province of Laos is located in the piedmont slope area with large undulations and fragmented terrain.The stratum is mainly composed of expansive soil and mudstone.After the site is leveled according to the design elevation,an artificial expansive soil high slope is formed around the plant site.Because the stability of the slope is directly related to the safety of the power plant,the consequence will be serious once there is damage.Therefore,this paper selects the typical slope to conduct stability evaluation of the potential slope damage through plane sliding and circular sliding.The evaluation results provide important basis for the design and treatment of the high slope of the power plant.

关 键 词：膨胀土 高边坡 平面滑动 圆弧滑动
