摘要
复杂基础的重力坝深层抗滑稳定计算是重力坝设计或复核的重难点。常规的刚体极限平衡法无法准确客观地寻找到最危险滑动面,该文以浙江省某水库重力坝为例,采用基于强度折减法的有限元分析,对正常蓄水位、设计洪水位和校核洪水位这三种工况分别进行了数值计算,计算稳定安全系数均能满足设计要求。通过本文实例,希望能为今后的类似工程设计提供一定的借鉴作用。
Anti-sliding stability analysis of gravity dam on complex foundation is a key point in gravity dam design.Regular limited equilibrium method can’t help to find the most dangerous failure surface exactly and objectively.In this paper,anti-sliding stability analysis of a gravity dam in Zhejiang is simulated by FEM under three different conditions,based on strength reduction method.Results show that the calculating safety factors meet specification requirements.The study results provide a reference for similar projects.
