摘　　要：结合某水坝工程6号与7号坝段坝体参数,采用两种计算方案分析了地基深层抗滑稳定性,重点计算了6号坝段第二层软弱夹层的情况,结果表明:最危险剪切破裂面的起始点在坝趾正下方,软弱夹层越深,抗滑稳定安全系数就越大,两坝段沿软弱夹层面的抗滑稳定最小安全系数均满足混凝土重力坝设计规范要求。Combining with the dam parameter of No. 6 and No. 7 sections of some dam project,the paper adopts the two kinds of calculation schemes,analyzes the deep sliding resistance stability of the foundation,mainly calculates the second interlayer of the dam section,proves by the result that the initial parts of the most hazardous plane is rightly under the dam address,and illustrates the deeper the weak interlayer,the bigger the stable and safety coefficient will be,and indicates the sliding resistance of the smallest safe coefficient of the weak interlayer between two dams can meet the demands of the regulation for concrete gravity dams.
