上部结构、地基和基础共同作用理论在逆作法设计与施工中的应用

逆作法施工是一种地上和地下两向同时施工的技术。根据其施工特点。将上部结构与地基、基础的共同作用理论于逆作法的设计与施工中，上部结构采用子结构法实现刚度和荷载向基础边界的凝聚，最后与基础和地基的刚度矩阵叠加，求解上部结构和基础的内力和变形。经算例分析，该方法合理可行。

APPLICATION OF THE REVERSEDESIGN AND CONSTRUCTION METHOD WITH A COMMON

The reverse construction method has been such a kind of construction technology,that the superstructure and substructure should be the commonly integrated and jointly combined together structure simultaneously.Based upon the characteristics of construction,the highrise building's superstructure,foundation bed and foundation work should be jointly integrated and commonly combined to form a monolithic structure,that is to say, the reverse design and construction method have been adopted for its construction.The superstructure has adopted the subsidiary structure method so that the cohesion of its rigidity and loading could have been duly combined with the foundation side.Eventually,the foundation bed and foundation work should be well added to the rigidity matrix,so that the internal stresses and their deformations of the superstructrue and foundation could have been obtained.In conclusion,according to analysis of practical examples,this method has been proved proper and practical.
