摘　　要：缅甸Dapein(Ⅰ)水电站厂房基坑地下水位埋深浅,对边坡稳定不利.在基坑四周采用防渗墙的基础上,对不同渗透系数的防渗墙进行了墙后浸润线计算,对设计提供的边坡采用剩余推力法、摩根斯坦法和严格Janbu法进行稳定性校核.结果表明,边坡稳定满足规范要求.分析成果对该工程基坑设计施工提供理论依据并得到了施工验证.A powerhouse of Depein(Ⅰ) Hydropower Station has the lower groundwater level.On the basis of using foundation walls around the foundation ditch,the saturation lines are calculated according to the different permeability of walls in this paper,and checked the stability of the original design of the slope using residual thrust method,Morgenstern law method,and strict Janbu method.The results show that the slope stability of the original design can not meet specifications,after the original slope is optimized and adjusted,it can meet the specification.The analyzed results provide theoretical basis for the design and construction of engineering foundation ditch.
