摘要
针对杨泗港长江大桥汉阳锚碇基坑开挖各阶段的施工过程,基于Midas GTS NX三维有限元分析软件,建立基坑开挖三维有限元仿真计算模型。通过Midas软件计算此基坑各开挖阶段的周围土体以及地下连续墙的数值,分析各开挖部位的受力特点和变形特征,得出基坑开挖过程中的最不利位置,为施工方在基坑开挖过程中采取相应措施提供参考。
This paper establishes a three-dimensional finite element simulation model for foundation pit excavation for the construction process of the excavation of Hanyang anchorage foundation of Yangsigang Yangtze River Bridge.The numerical analysis of the stress and deformation characteristics of each excavation site is carried out by Midas software,and the most unfavorable position in excavation process is obtained,which provide reference for the construction party to take corresponding measures in the excavation process.
