| 摘 要： | 通过对四川马家田尾矿的渗压试验，进行了尾矿孔隙比，上覆土压力和渗透系数的拟合分析，建立了尾矿的孔隙比与上覆土压力，渗透系数与孔隙比和渗透系数与上覆土压力三种数学关系，并进一步提出了尾矿的渗透系数与其埋深的数学模型，该模型适用于尾矿堆积坝和土石坝的渗透系数取值。

| Abstract: | In this paper,through the variant pressure permeability test of tailings of Sichuan Majiatian,the correlative analyses of void ratio ,cover earth pressure and permeability coefficient for tailings have been performed.Three correlative mathematical model of void ratio and cover earth pressure,permeability coefficient and cover ratio,and permeability coefficient and cover earth pressure for tailings have been constructed .A correlative mathematical model of permeability coefficient and embedment for tailings sand soil has also been put forward. The model is fit for the selection of permeability coefficient of tailings fill dam and earth-rock dam. |
