摘要

为了研究某尾矿坝在被采挖至坝顶180m标高时的渗流情况,采用有限元法对其三维渗流情况进行分析,并给出相应控制措施。经分析得出:该尾矿坝渗流稳定性较差,存在溃坝风险;为有效控制浸润面,可在初期坝附近设置一道排渗墙。
        In order to study the seepage situation of a tailings dam when it is excavated to 180 m elevation at the top of the dam, the threedimensional seepage stability of the tailings dam is analyzed by finite element method, and the corresponding control measures are given.Through analysis, it is concluded that the seepage stability of the tailings dam is poor and there is a risk of dam break; in order to effectively control the seepage surface, seepage drainage wall can be set near the initial dam.
