摘　　要：利用大型有限元软件SEEP-3D对某尾矿坝进行渗流稳定性计算,分别得出有无水平排渗管两种工况下的浸润面和水头等势线,并对此进行对比分析。计算结果表明,此尾矿坝在无任何排渗设施的情况下浸润面在坝坡溢流,而在加设水平排渗管后,浸润面明显下降到坝面以下,处于安全状态,故建议加设排渗设施。The seepage analysis to one tailing dam is made based on SEEP-3D,the infiltration surface and head equipotential line are got separately in the conditions of having horizontal seepage-exhaust tube or not,and the comparative analyses are made for them.The results show that the infiltration surface would overflow in dam slope for this tailing dam in no horizontal seepage-exhaust tubes,but if increasing the horizontal seepage-exhaust tubes,the infiltration surface would obviously decrease under the dam suface and be in safety,so it is adviced to increase the anti-seepage facilities.
