琵琶寺水库渗流有限元分析

Finite Element Analysis of Seepage in Pipa Temple

本文选取琵琶寺水库典型断面,采用有限元模型对琵琶寺水库坝体和坝基渗漏进行计算和分析。研究表明,水库主要通过坝基砾岩层向下游河床渗水;由于坝基黏土铺盖层、砾岩层厚度不同,不同坝段灌浆帷幕防渗效果存在差异。除险加固后,大部分坝段渗漏量显著减少,说明有限元分析法具有较大的成效。

In this paper, the typical section of Pipa Temple Reservoir is selected, and the seepage of dam body and foundation of Pipa Temple Reservoir was calculated and analyzed by finite element model. The results show that the reservoir seeps into the river bed downstream mainly through the conglomerate layer of dam foundation, and the antiseepage effect of grouting curtain in different dam sections is different due to the different thickness of clay cover and conglomerate layer of dam foundation. After danger removal and reinforcement, the leakage of most dam sections is significantly reduced, which shows that the finite element analysis method has great effect.
