香港广场深基坑围护结构变形的时空效应分析

介绍了上海香港广场深基坑围护结构的设计、施工与现场量测结果。在建立围护结构计算的的有限元分析模型和编制相应计算程序的基础上，对围护结构的变形进行了三维有限元分析与计算与计算，从而得出了围护结构水平位移的空间分布规律和随开挖时间延误而发生变化的规律，同时与现场量结果进行了对比。其方法和结论对软土深基坑的设计与开挖具有较为重要的理论意义与实用价值。

Time-space Effect Analysis on Deformation of the Retaining Structure of Deep Foundation Pit in Hong-Kong Plaza

The design,construction and field monitoring of retaining structure for a 12.3m deep excavation in Shanghai Hong Kong plaza are introduced in this paper.On the basis of setting up calculation FE model of retaining structure and developing three dimenional FE program,the deformation of the retaining structure is analyzed with three dimensional FE program.From this ,the space distribution and time dependent of displacements for retaining wall are obtained,and also are compared with measured values.The analytical method and corresponding conclusions gained have more important theoretical meaning and practical values in the design and construction of deep foundation pit in saturated soft clay.
