某水库坝下涵管渗漏分析及涵管出口坝坡稳定评价

摘要

针对广东某水库坝下涵管渗漏状况，运用有限元方法进行渗流模拟分析，结果可用于计算背水坡的稳定，进而制定水库运行的安全水位，为水库运行管理提供决策依据。根据水库多年运行水位数据计算分析，涵管位置背水坡的抗滑稳定是安全的。%Aiming at the culvert leakage under a dam in Guangdong province , finite element method has been applied to simulate culvert leakage .The numerical result can be used for back slope stability calculation , and the formulation of the reservoir operation safety water level .Its output will provide important basis for reservoir operation management .according to operation water level of the reservoir in many years , the stability against sliding of the dam is safe .
