Abstract: By using elasto-plastic finite element method (FEM) based on the technique of shear strength reduction (SSR), stability of slope reinforced with piles against sliding and the behavior of stabilizing piles in slope are numerically analyzed. The criterion of iteration non-convergence conventionally used for assessing the instability state of slopes is combined with that of the uncontrolled displacement at a certain characteristic node on the slope surface to evaluate the limit-equilibrium state of pile-soil-slope system, and its validity is demonstrated through comparative studies for typical example. Furthermore, a typical case slope reinforced with piles is investigated through numerical analyses. The results show that the potential slip surface determined by SSR-FEM is shallower than that by limit equilibrium method and limit analysis method for a slope reinforced with piles.

Key words: slope engineering, shear strength reduction technique, elasto-plastic finite element method, criterion of iteration non-convergence
