摘　　要：尾矿库排水构筑物是排泄雨洪水并回水的构筑物,该构筑物一旦遭到破坏,将造成严重危害。排水构筑物一般埋设在尾矿坝底部,其上覆盖尾砂最高可达100.0m以上,如何确定其上覆尾矿压力是结构设计过程中的关键问题,介绍了几种尾矿库排水构筑物上覆土压力常用计算方法,通过某算例分析,说明了其计算结果差异很大,最终给出了选择建议。The drainage structure of the tailings reservoir is the structure of the discharge of flood and the backwater,and it will cause serious harm once it is broken.Drainage structures generally buried in the bottom of the tailings dam,which is covered with tailings up to 100.0 meters high,how to determine the overlying tailings pressure is a key problem in the process of structural design,this paper introduces several calculation methods of soil pressure on tailings drainage structures,and gives suggestions to choose.
