吴岭水库土坝渗流及坝坡稳定性分析

Seepage and stability analysis of embankment of Wuling Reservoir

本文对湖北省京山县吴岭水库土坝进行了有限元渗流计算和坝坡稳定性计算,在分析大坝基础部位的残坡积土、强风化砂岩的强透水性和下游排水体对于大坝渗流场的影响的基础上,得出渗流是引起下游坝坡不稳定的主要因素,为大坝的加固处理提供了理论依据,也可供同类土坝设计时参考。

Seepage in embankment and stability of downstream slope are calculated for the Hydraulic Project of Wuling, Jingshan county, Hubei Province. On the basis of analyzing the influence of the strong perviousness of the eluvial slope soil and seriously weathered sandstone in foundation as well as the downstream drainage on the seepage field in the dam,the effect of seepage on the stability of downstream slope is analyzed. The finds will be the base for the future reinforcement of the dam and be useful for the future design.
