摘　　要：通过对尾矿库清基废料掺入适当比例不同性质的膨润土,模拟尾矿库现场防渗层渗透试验,取得同性质不同比例防渗层试样和同比例不同性质的防渗层试样的渗透系数,比较不同类型的防渗层试样的渗透效果和投资效益分析,为尾矿库清基废料再利用,重塑新型防渗层,代替75 cm黏土防渗层提供依据。By adding appropriate proportions of bentonite with different properties to the tailings pond cleaning waste and simulating the on-site permeability test of the tailings pond anti-seepage layer,the permeability coefficients of samples with the same property but different proportions of anti-seepage layer and samples with the same proportion and different properties of anti-seepage layer are obtained.The permeability effect and investment benefit analysis of different types of anti-seepage layer samples are compared,in order to reuse the tailings pond cleaning waste and reshape a new type of anti-seepage layer,provide a basis for replacing the 75 cm clay anti-seepage layer.
