库水位骤降情况下斜墙式土工膜防渗结构的稳定计算

The Sharp Drop in the Water Level under the Sloping Wall of the Structure of Impermeable Geomembrane Stability Calculation

在水库水位骤降情况下斜墙式坝体土工膜防渗结构稳定计算的传统方法有一定的不足,通过复合滑动面法对坝体土工膜防渗结构进行稳定分析,得出当水库水位骤降时坝体土工膜防渗结构在粘性垫层情况下的抗滑稳定安全系数的表达式。本文对此问题进行了精确的计算,可供设计人员参考。

Sharp drop in the water level in the reservoir under sloping wall of the dam impermeable geomembrane structural stability of the traditional methods of a certain lack of the compound on the sliding surface of the dam structure impermeable geomembrane stability analysis, when the reservoir water level at first impermeable geomembrane down at the dam structure in the ease of viscous layer of safety factor of stability against sliding expression. This paper conducted a precise calculation, for the reference design.
