黄壁庄水库土坝渗流的有限元分析

Finite element analysis of seepage through the earth dam of Huangbizhuang reservoir

我国修建于上世纪五六十年代的水库,经过多年的运行,均存在不同程度的问题,需要对其进行检测、评估。其中,土坝渗流问题是引起土坝破坏的主要原因之一。因此,准确计算土坝渗流的自由面和渗流量是非常必要的。研究利用有限元的方法,对均质土坝的稳定渗流进行了分析,并运用于黄壁庄水库大坝,为今后该大坝的工程管理、安全监控及加固提供了理论的依据。

Many problems have appeared in the earth dams constructed in 1950's or 1960's in our country. These dams need to be analyzed and evaluated once more. The seepage through earth dams is the main reason of dam destruction. It is necessary to calculate the free surface and the amounts of seepage. In this paper, the steady seepage through earth dams is analyzed with the finite element method and the seepage through Huangbizhuang earth dam is analyzed. Based on the result of the calculation, many reasonable suggestions are posed to help the management and reinforcement of Huangbizhuang Reservoir earth dam.
