摘要
以Ｐｏｕｌｏｕｓ弹性理论法为基础，假定桩、土之间位移协调，计入深基坑开挖过程中土体隆起对地下连续墙、中间支承桩上抬的影响，考虑逆作法施工过程中地下连续墙—中间支承桩—地下室楼板—上部结构共同作用。并对某大厦逆作过程的结构进行了计算，将理论计算结果与现场实测结果进行了比较分析，说明理论计算方法的可行性。
According to the computational method in reference 1,this paper analyzed the computation of Hengji Building during its top-down construction,and compared the calculated result with its measured value.It proved the feasibility of the method of computation in reference 1.
