摘要
通过对北京地铁16号线穿越万泉河立交桥工程进行研究,分析了桩基托换技术的施工工艺、关键技术、经验与特点等。通过采用MIDAS等有限元软件建立有限元模型进行计算分析,为桩基托换工程沉降控制提供指导,解决了在实际工程中遇到的若干技术问题。
Based on the study of the project of Beijing metro line 16 crossing Wanquanhe overpass,this paper analyses the construction technology,key technology, experience and characteristics of pile foundation underpinning technology, establishes the finite element model by using MIDAS finite element software software, and provides settlement control for pile foundation underpinning project. Guidance has solved some technical problems encountered in practical projects.
