【摘要】 本文结合上海外滩金融中心大型深基坑工程，采用动态施工反演分析法，分析了中隔墙和支撑体系在施工过程中的受力状况及墙体的稳定性，并且对墙体位移和内力进行及时预报，为基坑工程信息化施工反馈提供依据，从而保证了支撑及整个基坑工程安全。更多还原

【Abstract】 To the big deep excavation of Shanghai Bund Finance Center project, the elastic moduli of each soil ground are obtained by the backward analysis method of FEM with the function of staged construction simulation. Furthermore, the forces acted on the mid-wall and struts during the course of the construction are calculated, with the displacements and internal forces of wall in the coming construction stages are forecast. So this study provides basis for the informationalized construction of deep excavation and guarantees the dafety of struts and the whole pit foundation.更多还原
