Finite Element Analysis of Dam Foundation Seepage Effect on Cutoff Wall Depth of Guxue Concrete Gravity Dam

Abstract:

This paper is committed to analyze the results of numerical simulation in the dam foundation seepage field of Guxue concrete gravity dam with the finite element method. The results show that the cutoff wall depth of the Guxue dam foundation seriously impacts the seepage effect of cutoff wall. The cutoff wall initially becomes deeper, the reduction of seepage discharge is distinct to reach 24%, as the depth increases gradually, the seepage discharge reduces slowly and can only reach 7%. In a word, the cutoff wall depth of Guxue concrete gravity dam exists a reasonable value and the numerical result is15m in this paper.
