摘要
为解决市政道路改扩建工程中桥梁加宽桩基础差异沉降的技术问题,文章通过数值仿真分析软件构建了桩-土相互作用下有限元模型,分析了加宽桥梁桩基础承载特性及桩基础沉降变化规律,提出增加桩长的桩基础沉降差异控制技术。
In order to solve the problem of differential settlement of widened pile foundations in the reconstruction and expansion of municipal roads,the finite element model of pile-soil interaction is constructed by numerical simulation analysis software.The bearing characteristics of widened bridge pile foundation and the settlement of pile foundation are analyzed.According to the law,the difference control technology of pile foundation settlement with increasing pile length is proposed, and the research results can be used for reference and reference of similar projects.
