摘要
选取河南某中线法尾矿库的两种尾矿砂:底流样尾矿砂和溢流样尾矿砂,通过三轴固结排水(CD)剪切试验,得到了两种尾矿砂样的邓肯-张E-B模型的试验参数。试验的结果可为该尾矿坝的数值模拟分析提供参考。
Two kinds of tailing sands of a midline tailing pond in Henan province,bottom flow tailing sand and overflow tailing sand,were selected and the test parameters of Duncan-Chang E-B model of two kinds of tailing sand samples were obtained through triaxial consolidation and drainage(CD)shear test.The experimental results can provide a parameter source for the numerical simulation analysis of the tailings dam.
