N2 - In most of the past research which reference to stabilizing piles, the horizontal semi-infinite soil grounds were utilized to analyze the response of the stabilizing piles due to lateral soil movement or lateral force loading on piles. Meanwhile, the conclusions obtained from the flat soil grounds are applied in slopes to estimate the lateral force acting on stabilizing piles. The prediction by these models can roughly satisfy with the observed values. However, in order to analyze the response of stabilizing piles due to the sliding of slopes more accurately, the incline of the soil ground should be taken into account. In the present paper, the soil arching effects between two neighboring stabilizing piles which embedded in a semi-infinite granular soil slope is analyzed, and meanwhile the lateral active stress in the rear of piles is obtained. Furthermore, the squeezing effect between two piles proposed by Ito and Matsui are combined with lateral active stress in the slope to evaluate the distribution of the lateral force of stabilizing piles in sandy slope. A numerical simulation given by FLAC3D is utilized to validate the proposed approach, which shows that the proposed model could reasonably predict the lateral force acting on stabilizing piles embedded in slope.
