摘　　要：随着结构工程技术的发展,逆作法已日益广泛应用于钢-混凝土组合结构技术体系中,可显著降低水平支撑、竖向支撑构件施工技术难度,加快施工速度,并避免上层楼盖模板拆除安全问题,有着良好的社会经济效益。阐述了钢-混凝土组合核心筒(剪力墙)逆作法、中心岛+局部逆作法两种地下空间新型逆作法结构体系,并通过实际工程介绍新型逆作法多项技术的联合应用,突破传统逆作法技术应用的局限性,较好地解决工程逆作法施工难度大、工序复杂、施工质量难以保证等难题,为今后同类型项目逆作法设计提供借鉴。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.
