高承台桩基的动力屈曲分析
Dynamic bucking analysis of pile foundations with elevated caps
摘要
Abstract
In order to obtain the dynamic displacement diagram of a node under the dynamic Bucking Analysis of Pile Fountdations with Elevated Capsand use the B-R criterion to judge the stability of the pile foundation of the high bearing platform. This paper presents a simplified method to apply the finite element model to the dynamic buckling analysis of the pile foundation with high bearing platform. The basic equations of the nonlinear dynamic buckling problem of the high pile foundation pile based on the Galerkin method are established. The results of the fourth-order Runge-Kutta method are used to verify the correctness and applicability of the simplified finite element method. The model of pile foundation with different pile diameter, pile length and pile is established and analyzed. The results show that the simplified finite element method has a certain feasibility and practicability for the dynamic buckling analysis of high pile foundation pile. Which provides a new method for the dynamic buckling analysis of the pile foundation.关键词
