摘　　要：以云南某尾矿库工程为研究背景,针对尾矿坝稳定性日渐变差等问题,采用三维数值模拟、堆坝模型试验的浸润线分析结果和室内渗透系数试验等方法,根据室内土工实验的尾矿体渗透系数实验结果,参考国内外尾矿坝渗流计算的渗透系数经验值,考虑到尾矿坝中尾矿体的各向异性问题,选取合理的计算参数,分析尾矿库在不同工况下尾矿坝浸润线的埋深与变化规律。研究表明:试验结果与三维数值模拟计算结果较吻合,能够反映真实情况。Taking a tailings pond project in Yunnan as a research background,address to the daily variation of the stability of the tailings dam,three-dimensional numerical simulation,the analysis of the infiltration line of the dam-filling model test,and the indoor permeability coefficient test are used.The experimental results of the tailings body permeability coefficient and the empirical values of the permeability coefficients calculated with reference to the seepage flow of the tailings dam at home and abroad,considering the anisotropy of the tailings body in the tailings dam,select reasonable calculation parameters,the differences between the tailings reservoir burial depth and variation law of infiltration line of tailings dam under working conditions are analized.The research shows that the test results are in good agreement with the three-dimensional numerical simulation calculation results and can reflect the real situation.
