【摘要】 基于曼远铁矿尾矿库地质勘察资料,合理概化了坝体主轴剖面,采用非线性本构模型,对处于洪水工况运行条件下的曼远铁矿尾矿坝渗流场进行了数值模拟分析,并在尾矿坝渗流分析的基础上,研究了洪水与水平地震共同作用下该尾矿坝的动力响应规律.计算分析结果显示,该尾矿坝可在特殊工况下稳定运行.更多还原

【Abstract】 Based on the geological prospecting data of Manyuan Iron Ore Tailings,this paper generalizes the dam axis section in a reasonable manner,applies numerical simulation methods to analyze the seepage field of the tailings dam on the condition of flood. According to the seepage data,it studies the dynamic response of the tailings dam co-functioned by flood and horizontal earthquake. Through calculation and analysis the results show that the tailings dam can operate well under the unfavorable condition.更多还原
