摘要
采用同济曙光有限元分析软件,对某地铁站基坑工程进行了换撑和不换撑方案动态施工全过程数值模拟,重点分析了两种不同施工方案对基坑周边地表沉降、地下连续墙侧向位移、钢支撑轴力、地下连续墙和主体结构受力的影响,并与现场监测数据进行了对比。分析结果表明,该基坑工程采用不换撑方案进行施工,理论上可行。
Authors adopted one Tongji Shuguang finite element analysis software to simulate whole dynamic construction processes of two plans,changing-support and no-changing-support,of the foundation pit project of a subway station.In this article,they analyze influence of these two plans on sedimentation of peripheral ground surface around the foundation pit,side displacement of underground diaphragm walls,axis forces of steel supports,stress of underground diaphragm walls and main structures and so on,and also compare these analysis results with on-site monitoring data.Analysis results indicate that it is theoretically feasible to adopt the no-changing-support construction plan in this foundation pit project.
