Abstract

To analyze the impact of stress and seepage field coupling effect on the stability of the tailings dam, Finite element analysis software MIDAS-GTS, build analytical models Mohr-Coulomb criterion. Coupling of different pile heights than the stress field and seepage field analysis of the tailings dam at the same slope, by limit equilibrium method and finite element analysis of tailings dam stability strength reduction. By comparing the results of the analysis showed that the two methods: In the same conditions, the limit equilibrium method and finite element strength reduction conclusion is consistent; Meanwhile in the slope ratio unchanged, with an in-crease in the accumulation of the tailings dam dam dam safety factor decreases, is not conducive to the tailings dam safety. The results for the tailings dam design and practical use has a certain value.
