| 摘 要： | 通过相关物理力学试验,分析了尾砂的物理力学性质,用Geo-Studio有限元软件计算和分析降雨条件下尾矿坝的浸润线。通过Slide软件,用极限平衡法中的简化Bishop法和瑞典法对降雨条件下尾矿坝的稳定性进行分析。结果表明,尾矿坝在现状高程下,其坝体在正常运行、洪水运行和饱和运行工况时计算的安全系数均能满足规范要求,计算得到的稳定性滑面大多是经过坝体最底部的深度滑弧面,且滑弧面范围较大。

| Abstract: | In this paper, the physical and mechanical properties of tailings are analyzed by related physical and mechanical experiments, and the saturation line of tailings dam under rainfall is calculated and analyzed by Geo-studio finite element software; the stability of tailings dam under rainfall is analyzed by Slide software, simplified Bishop method and Swedish method in limit equilibrium method. The results show that the safety factor of tailings dam can meet the requirements of the code under normal operation, flood operation and saturated operation. The calculated stability sliding surfaces are mostly deep sliding surfaces passing through the bottom of the dam, and the scope of the sliding surface is large. |
