Abstract:By using elasto-plastic finite element method based on the technique of shear strength reduction, stability of slope reinforced with piles and performance of load-bearing piles in slopes subjected to combined load are numerically analyzed. The iteration non-convergence criterion conventionally used for assessing the instability state of slopes is employed to evaluate the limit-equilibrium state of pile-soil-slope system. Moreover, considering the complexity of pile-soil interaction, the criterion based on the uncontrolled displacement at a certain characteristic nodes on the slope surface is used for evaluate the limit state as an assistant criterion in addition to the iteration non-convergence criterion of solution in order to get more reasonable and reliable solution from numerical results. Finally, the effect of the combinations of vertical load and horizontal load on the stability of pile-soil-slope system is investigated through numerical analyses.
