结合ANSYS大型有限元分析软件，以双河水电站拦河闸坝为例，研究了深厚覆盖层及复杂地基情况下闸基的渗流特性，通过计算分析得出不同工况下各种组合的渗漏量、坡降、渗压随防渗帷幕深度变化情况。结果表明：在现有防渗措施下，墙后覆盖层内渗流量均不大，渗透坡降均很小，满足渗流稳定性要求，对覆盖层地基和两岸分别采用的防渗墙和帷幕灌浆防渗处理措施效果良好。

Combining with the large finite element analysis software ANSYS,taking the Shuanghe Hydroelectric Project Sluice as an example,the paper studied the gate base seepage characteristics with deep overburden and complex foundation. Through the calculation analysis under different working conditions,all kinds of combinations,obtained the seepage flow,seepage slope and seepage pressure with impervious curtain depth change. The results show that under the existing anti-seepage measures,the seepage flow is not large,seepage slope is very small in the overburden behind the wall,which meets the seepage stability requirements. The effect of using the cut-off wall and curtain grouting anti-seepage treatment measures of the two sides and the covering foundation are good.
