Abstract

Abstract

In order to reasonably select probabilistic slope stability analysis methods, a comparison research on the global minimum method and the overall slope method was carried out based on vertical slice limit equilibrium method software SLIDE and geotechnical centrifuge model test of embankment on sloped weak ground. The overall slope method was used to get the influence rule of anti-slide pile reinforcement on the stability of embankment on sloped weak ground. The research result shows that compared with the global minimum method, the overall slope method has a strict algorithm, more and conservative results, but more time consumption. The selection and application of the two probabilistic slope stability methods should depend on the model complexity and the analysis goals. The overall slope method can prove the effectiveness of anti-slide piles for embankment reinforcement on sloped weak ground well.
