摘要
Abstract
For the existing calculation methods for the stabilising pile,the interaction between pile and landslide body is simplified as the determined load.However,these methods all ignore the direct dependence of the interaction on the displacement of the pile.This study developed a method,in which m-method model was employed to simulate the interaction between landslide body and pile.Meanwhile,equations were established for the piles above and below the slip surface respectively,and their expressions of displacement and internal force were also solved with power series method.Meanwhile,the bending moment and shear force at the slip surface were obtained by using deformation coordinating conditions of the upper and lower piles at the sliding surface.Hence,the deformation,internal force of the pile and the interaction between pile and landslide body were easily computed.Finally,an example was calculated by the presented method and FEM,respectively.It was found that results were in good agreement,which verified the correctness of the method.关键词
