Based on the Finite Element Limit Equilibrium Method Analyze Earth-Rock Dam Slope Stability

摘要

Based on finite element limit equilibrium method, taking a core embankment dam construction period as the research object and studying on the dam slope stability. Combined with SIGMA/W and SLOP/W module, at first analyze the finite element stress with SIGMA/W module, then, the results are imported into the SLOP/W module to calculate the slope stability factor, and compared with the results of using rigid limit equilibrium method. The results show: There is a small difference in slope stability factor in these two methods. Finite element limit equilibrium method can be applied to earth - rock dam slope stability analysis and researches have some reference significance for practical engineering slope stability.
