某山谷型尾矿库三维渗流场模拟分析

Numerical Simulation on the Three-dimensional Flow Field of a Valley-type Tailings Pond

某尾矿库的尾矿沉积规律复杂多变,使得尾矿库的渗流场异常复杂。通过三维渗流有限元方法对该尾矿库现状堆高以及最终标高情况下的渗流场进行了模拟分析,对尾矿库后期的安全管理具有较大的指导意义。

The deposition law of tailings in tailings pond is complex and ever-changing, which makes tailing seepage field more complicated. The method of three dimensional flow field is more applicable on seepage flow characteristic simula- tion of the tailings. The three dimensional seepage finite element method is used to simulate the seepage field high status and the final level of tailings pond, which has a significant guidance for tailing pond＇s later security management.
