逆作法施工方法是通过建筑物地下连续墙、逆作柱及地下室结构各层梁板的组合形成稳定的支护体系 ,使地上、地下结构工程能同时交叉施工的施工方法 ;它不但能缩短整体结构的施工周期 ,降低挡土结构的工程成本 ,增大施工空间和施工工作面 ,而且还可以保证施工过程中相邻建筑物的 The reverse construction method is to form a stable support system through the combination of the continuous diaphragm walls of the building, the inverted columns and the basement floor, and the construction method that the above-ground and underground structure works can be crossed at the same time. It not only shortens the overall construction Structure of the construction cycle, reducing the cost of retaining the structure of the project, increase the construction space and construction work surface, but also to ensure that the construction process of adjacent buildings
