| 摘 要： | 尾矿库加高扩容，需对尾矿坝进行稳定性评价。依钻孔资料，结合加高设计方案，建立尾矿坝地质模型。对洪水及地震作用双重工况下，应用强度折减法进行了尾矿坝渗流稳定性、静力稳定性和动力液化稳定性计算。结果表明，浸润线没有从坝坡出溢，渗流稳定。从坝体动力反应及液化结果得出该坝是动力稳定的，安全系数满足规范要求。本研究基于有效应力原理，结果对尾矿坝渗流、静力及动力稳定性评价方面有一定的借鉴意义。

| Abstract: | For the heightening designing of tailings dam,the dam's stability assessment is needed.In accordance with the borehole data,by combined with the heightening design scheme,the geological model of the tailings dam is established.Tailings dam's seepage stability,static stability,and dynamic stability under the flood and earthquake work condition are calculated.The results show that there is no infiltration of the overflow from the slope and the seepage is stable;the safety factor meets the regulatory requireme... |
