A Study on the Correction of Analytical Solution for Wetted Tailings Reservoir Saturation Line
The saturation line is one of the main factors affecting the stability of tailings ponds,and accurate prediction of the saturation line position is of great significance for preventing the instability of tailings points.In response to the analytical solutions proposed in existing literature for wet tailings ponds,the downstream boundary condition equations were modified using Kochina's theory and Falkov-ichs theory.Combined with the modified upstream and downstream boundary conditions,the analytical solution for the revised saturation line of the tailings pond was obtained.A working condition model was established using finite element software with bottom slopes of 0.05 and 0.1,as well as initial slope ratios of 1∶2,1∶1.5,1∶1,1∶0.577(60°),and 1∶0.5.The analytical solution proposed in the paper was compared with numerical and literature analytical solutions,and the results showed that the proposed analytical solution had higher accuracy and wider applicability.
