摘要
深大基坑开挖施工过程中,围护结构的内力与变形分布研究是保障基坑和支护结构稳定性的重要措施之一.以某城市房屋深基坑为工程依托,对其在开挖过程中的监测数据进行了分析,并采用ANSYS软件建立了基坑开挖过程的有限元模型,通过将模拟计算数据与监测数据进行对比分析,得到基坑支护结构位移和内力的变化规律.结果表明,监测结果与模拟结果基本一致,该基坑支护结构设计合理.
In the process of excavation of deep/large foundation pit,research on distribution of internal force anddeformation of the retaining structure is an important to guarantee the stability of foundation pit and the supportingstructure. Relied on the engineering support of deep foundation pit of a certain city building,the monitoring data inthe excavation process were analyzed,and the ANSYS software was used to establish the finite element model ofexcavation process. Comparing the data calculated by simulation and monitoring data,we obtained displacement andinternal force variation laws of foundation pit supporting structure. The results show that monitoring results andsimulation results are basically identical,the foundation pit supporting structure design is reasonable.
