| 摘 要： | 单桩的P－S曲线特征，是桩受力特征的宏观表现。研究桩体在不同荷载作用下的P－S曲线特征是揭示桩体受力机理的主要途径。文中通过有限元模型分析了桩长、桩径、桩体弹性模量和压缩模量等因素对单桩P－S曲线的影响，为桩基础的设计与施工提供依据。

| Abstract: | P-S curve characteristic of single pile is the macro performance of pile stress characteristics.Study on P-S curve characteristic of pile body under different loads is the main approach to show pile stress mechanism.This paper analyzes the influence of pile length,diameter,elastic modulus and compression modulus on P-S curve of single pile through finite element model,which provides reference for design and construction of pile foundation. |

| Keywords: | pile foundation P-S curve elastoplastic contact finite element analysis |
