Abstract:With the development of structural engineering technology, the reverse construction method had been increasingly widely used in the steel-concrete composite structural technology system, which can significantly reduce the technical difficulty of horizontal support and vertical support member construction, speed up the construction speed, and avoid the safety of the upper floor formwork removal. It had good social and economic benefits. The steel-concrete composite core tube (shear wall) reverse construction method, central island + local reverse construction method these two new reverse construction structural systems of underground space were described. Through practical engineering, combined application of new reverse engineering techniques was introduced, which can better solve the problems of difficult construction, complicated procedures, and difficulty in ensuring the construction quality of engineering using  reverse construction method, and provide a reference for the design of similar projects in the future.Keywords:reverse construction method; steel-concrete composite core tube; new central island+local reverse construction method; separated steel-concrete composite shear wall; steel-concrete composite anti-side continuous wall
