某尾矿库三维渗流分析

针对某尾矿库具体条件，采用三维有限元模拟和渗流场分布计算，判明在概化模型理想条件下尾矿坝三维渗流浸润线埋深的特点；通过对各排渗结构参数的敏感性进行分析，确定影响坝体浸润线埋深主要因素。模拟结果表明：在各排渗结构功能正常的工况下，尾矿库浸润线在尾砂子坝段的埋深均在15 m以下，大于规范要求值。

3D Seepage Analysis of a Tailings Dam

In view of specific conditions of some tailings dam，three-dimensional finite element simulation method and the computing of seepage field distribution were adopted to fix the features of 3D seepage line depth of tailings dam under ideal conditions of a generalized model; Through analyzing the structural parameters' sensitivity of the seepage drainage，the main factors for impacting the dam seepage line depth were determined. The simulation showed that under the normal working of each drainage structure in function，the depth of tailings seepage line at tailing sub-dam is 15 m below，which is higher than the required value by the specification.
