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。以某城市地铁车站深基坑为工程依托,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。During the excavation of deep foundation pit, study on the deformation and internal force of supporting pile and brace is one of the important measures to guarantee the stability of foundation pit and supporting structure. Basing on the deep foundation pit of subway station, the monitoring data in excavation is analyzed, finite element model of the foundation pit is established by using ANSYS software, deformation and internal force of the supporting structures are studied by comparing the simulating data and monitoring data. The results show that monitoring results and simulation results are basically identical, and the supporting structure of the foundation pit is designed reasonably.
