Analyses of the lateral force on stabilizing piles in sandy slope

In the past, horizontal semi-infinite soil grounds were utilized to analyze the response of the stabilizing piles due to lateral soil movement or lateral force loading. In this study, a limit equilibrium method analyzing the lateral force on stabilizing piles that embedded in semi-infinite slopes is presented. In addition, the soil arching effects between two neighboring stabilizing piles are analyzed, and the lateral active stress in the rear of the piles is obtained. Furthermore, the squeezing effect between the two piles proposed by Ito and Matsui is combined with the lateral active stress in the slope to evaluate the distribution of the lateral force of the stabilizing piles in sandy slopes. The numerical simulation using FLAC^3D is utilized to validate the proposed approach. The simulation shows that the proposed model could reasonably predict the lateral force acting on the stabilizing piles embedded in the slope.
