摘要
浸润线是影响尾矿坝稳定性的主要因素之一,采用seep/w有限元渗流分析软件计算出不同渗透系数比的尾矿堆积坝浸润线。结果表明,当上下层尾砂的渗透系数比大于100时,下层尾砂显现出较强的阻水作用,浸润线得到抬升,为优化尾砂渗透系数比提供了依据。
Saturation line is one of main factors influencing stability of tailings dams.The finite element analysis software seep/w is used to calculate saturation lines with different permeability coefficient ratios.The results show that high resistivity water occur in lower layer tailings when the permeability coefficient ratio between up and lower tailings is over 100,and saturation line can be lifted,which can provide basis for optimization of permeability coefficient ratio.
