Abstract

A number of engineering activities are potentially threatened by adjacent slopes, and stabilizing piles as a simple and effective method can prevent and control potential landslides. However, when soil resistance conditions are not adequately considered, it can result in inconsistencies between theoretical calculations and engineering practice. Therefore, this paper established a parabolic landslide thrust and soil resistance distribution model based on the field model test and discussed their resultant force action point locations. Moreover, the calculation model and governing equation of the stabilizing pile considering nonlinear landslide thrust and soil resistance under three failure modes were established. Additionally, the general solution forms of the pile deformation and force obtained by the power series method were discussed under different soil pressure distributions. The results calculated by the method considering the nonlinear landslide thrust and soil resistance were in better agreement with the actual stress mode for single-row stabilizing piles according to the model results and two case studies. The newly proposed calculation model provides a new idea for the design and calculation of the single-row stabilizing piles on the loess slope.
