摘要
人某超深桥墩基坑工程采用双排桩加钢管围堰(三道钢管内支撑),采用常规的基坑设计软件无法直接进行计算分析.利用专业的通用岩土分析软件Midas GTS NX对基坑开挖全过程进行三维有限元模拟,数值模拟结果可以显示基坑支护周边地表变形情况、结构变形及内力情况,进而分析基坑设计的合理性与安全性.
Abstract
An ultra-deep pier foundation pit engineering adopts double-row piles and steel pipe cofferdam(three steel pipe internal supports),which can not be directly calculated and analyzed by using conventional foundation pit design software.Three-dimensional finite element simulation of the whole process of foundation pit excavation is carried out by using the professional general geotechnical analysis software Midas GTS NX.The numerical simulation results can show the surface deformation,structural deformation and internal force around the foundation pit support,and then the rationality and safety of foundation pit design are analyzed.
