摘　　要：在水库水位骤降情况下,坝体土工膜防渗结构稳定分析的传统方法有一定的不足,通过折线法对坝体土工膜防渗结构进行稳定分析,得出在水库水位骤降情况下坝体土工膜防渗结构的抗滑稳定安全系数的表达式,并对此问题进行了精确的计算,可供设计人员参考。Under the conditions of sudden drop of reservoir water level, the traditional method of stability analysis of impermeable geomembrane structure has some shortcomings. The broken-line method was used to make the stability analysis of impermeable geomembrane structure in the clam body and then gained the expression of safety coefficient of stabil- ity against sliding of mentioned geomembrane structure, Then a precise calculation was made, which could be used for reference for the designers.
