摘要
基于ABAQUS大型有限元软件,以港珠澳大桥珠海连接线拱北隧道明挖段深基坑工程为依托,以基坑变形理论为基础,通过数值模拟对基坑稳定性进行分析,得到基坑开挖引起的地连墙水平位移、周边地表沉降、基坑底部隆起变形规律,对后续类似工程具有一定的借鉴意义。
Based on ABAQUS large-scale finite element software and the foundation pit deformation theory, the stability of Gongbei Tunnel foundation pit is simulated. Through analyzing, the laws of diaphragm wall displacement, surface settlement and uplift of bottom are obtained. It is of great reference significance for similar deep and complex foundation pit
