摘要

静力压桩过程是一种稳态贯入过程。该过程使得桩周附近区域的土体产生较大挤压作用，并出现了较大变形，因而基于传统小变形的有限元分析与真实的贯入过程有着较大的误差。基于更新的拉格朗日列式法，分析压桩时产生的大变形，引入桩-土界面间的接触作用，桩周土体采用Mohr-Coulomb模型，并运用有限元方法进行数值分析，较好地实现了静力压桩过程的数值模拟。

Abstract

Static piling is the procedure of steady penetration which leads to great compression and large deformation of the soil adjacent to the pile. And it is reasonable that there are errors between the real penetration and the finite element analysis according to traditional small deformation. so new finite element method used to analyze large deformation during piling is presented. The method is based on updated Lagrangian formation (ULF)

considering the contract between pile and soil

regarding soil as the Mohr-Coulomb model. The numerical results show that the method can realize the numerical simulation of static piling.
