Experimental Research on the Dissipation Law of Pore Water Pressure of the Loess Basement Refuse Dump

摘要：

　　After determining the pore water pressure and establishing the dissipation equation for it,this paper conducts on-site sampling of the loess from the Antaibao opencast mine dump,trying to simulate the actual situation and carry out experiment for the dissipation of pore water pressure in the laboratory.The degree of decrease control equation,dissipation control equation of pore pressure and dissipation time equation are thereby obtained.By a comprehensive analysis,the dissipation law of the pore water pressure of undisturbed saturated loess affected by outer loads is obtained:the dissipation time of pore water pressure is prolonged with the increase of the confining pressure,the degree of decrease increases with the confining pressure,and the dissipation coefficient also shows an increasing trend with the moisture content.
