摘要： 渗流场是影响尾矿坝安全性和稳定性的重要因素之一。依托具体工程，根据正常洪水位和最高洪水位两种工况，采用三维有限元方法，对坝体渗流进行计算分析，确定了渗流坡绛和浸润线位置，计算结果显示两种工况下渗流场总体趋势相近，变化不大。

Abstract: The seepage field is one of the important factors that affect the safety and stability of tailings dams. This paper presents the numerical tailing dam stability analysis results. The seepage analysis considers the site specific subsurface conditions under normal flood and design highest flood conditions. The resultant phreatic lines and seepage gradient are obtained. It is concluded that under two different flood levels, the seepage fields of the tailing dam are similar.

Key words: Tailing Dams, Seepage Fields, Seepage Gradient, Phreatic Lines
