桥墩附近基坑开挖对桥墩基础影响的数值分析

Numerical analysis on the impacts of foundation pit excavation nearby bridge pier on bridge pier foundation

以高铁桥墩边地铁基坑围护设计为研究对象,借助有限元程序分析基坑开挖过程中对高铁桥墩桩基础的变形影响,对后期施工监测提出了理论指导意见,以期保证施工安全,杜绝安全事故隐患。

Taking subway foundation envelop design surrounding high-speed railway bridge pier as the research target,making use of finite element program,it analyzes the deformation impacts of foundation excavation process on high-speed railway bridge pier foundation,and proposes theoretic guiding advice for late construction monitoring,with a view to guarantee construction security and to removal security hazards.
