摘　　要：文章采用MIDAS/GTS软件,运用初流量法,选取合适的边界条件对某尾矿坝各个分区及渗流系统包括地下水导排管、防渗膜、排水棱体、截渗坝等进行了三维有限元模拟.选取13个垂直于堆积坝坝轴线的典型剖面绘制渗流场分布图,对渗流场分布、渗流量、渗透梯度等进行计算分析,并得出合理结论,可为类似工程提供参考.This paper adopts MIDAS/GTS software,using the initial flow method,three-dimensional finite element simulation of each subarea and seepage system of a tailings dam,including groundwater conduit,impervious membrane,drainage prism and cutoff dam,was carried out by selecting suitable boundary conditions.Selecting 13 typical sections perpendicular to the axis of the dam to draw the distribution diagram of the seepage field,the distribution of the seepage field,the seepage quantity and the seepage gradient are calculated and analyzed,and the relevant conclusions are drawn,the conclusion can provide reference for similar projects.
