STABILITY CALCULATION OF PILE-REINFORCED SLOPES BY THE LIMIT EQUILIBRIUM METHOD CONSIDERING SLIDING RESISTANCE OF PILES ACCORDING TO ITO-MATSUI METHOD

Abstract

In the study, advantages and disadvantages of the calculation methods for overall sliding stability of pile-reinforced slopes considering sliding resistance of pile were summarized and analyzed. An automatic program for stability calculation of pile-reinforced slope was established based on the limit equilibrium method considering sliding resistance of piles according to Ito-Matsui method. The program was used to evaluate the effects of the piles, such as position and spacing of the piles on the stability of the slopes.
