摘　　要：沉降差控制是软土地区逆作法施工中的关键技术。根据逆作法施工特点,采用上部结构、地基和基础共同作用理论,对算例进行计算,根据结果,分析沉降差与上部结构、地基刚度贡献以及地下连续墙深之间关系,以使逆作法施工控制中有的放矢,减少沉降差带来的负面影响。The control of settlement difference is a key technology of up-side-down construction adopted for soft soil foundation. Based on the characterices of up-side-down construction,the theory of interaction between superstructure and subgrade in used for caculating the settlement difference. By the analysis of the relationship between the stiffness of superstructure ,subsoil,the depth of diaphragm wall and the settlement difference,the methods of controling the settlement difference are discussed.
