摘　　要：土坝渗透破坏是很多病险水库失事的主要原因,通过二维有限元法对土坝进行渗流计算、分析坝体渗流场、进行合理的大坝安全评价显得尤为重要。文章以西泉眼水库为例,基于二维有限元法对比分析大坝除险加固前后的土坝渗流状态,取得土坝浸润线的位置及渗流形态,为大坝安全评价及水利工程设计提供判断和设计依据。The seepage failure of earth DAMS is the main cause of many dangerous reservoir accidents,it is very important to calculate and analyze the seepage field of earth dam by two-dimensional finite element method.In this paper,xiquanyan reservoir is taken as an example,and the seepage state of earth dam before and after dam reinforcement is compared based on two-dimensional finite element method,and the position of seepage line and seepage form of earth dam are obtained,which can provide judgment and design basis for dam safety evaluation and hydraulic engineering design.
