Abstract
The static stability evaluation of tailing dam is one of the most important tasks in the mine environmental protection project. The methods for the static stability calculation were discussed in this paper, which were Swedish Circle Method, Janbu Method, Bishop Method, Finite Element Method and Strength Reduction Finite Element Method (SRFEM) with five different failure criterions considered. The analysis results show that the failure sur- face simulated by SRFEM was closed to the result of classical method, and the safety factor by SRFEM with D-P3 failure criterion was much more closed to the one got from the Felleni- us Method. So, it is feasible to evaluate the static stability of tailing dam through SRFEM. Also, it indicates that the finite element method and SRFEM are suitable to simulate practical engineering with the complicated cross section and non-linear materials.
