二陈水库大坝安全鉴定中渗流模拟分析
Seepage Simulation Analysis in the Dam Safety Appraisal of Erchen Reservoir
摘要
Abstract
Taking Erchen Reservoir as an example,due to severe leakage at the foot of the dam,there is no reverse filtration protection at the downstream dam slope seepage outlet,which poses a risk of seepage damage.This paper uses Autobank design software to numerically simulate the seepage stability of dams.The results indicate that the overall seepage inside the dam is stable,and the seepage gradient at the downstream dam slope escape point is less than the allowable value.However,the local water slope at the back of the dam is steep,resulting in leakage.The seepage safety assessment of the reservoir dam is rated as"C level",providing a basis for dam reinforcement.关键词
