It is self-evident that the deep foundation pit has an impact on the safety of surrounding existing buildings. This paper will introduce a new construction method: the semi-reverse construction technology combining the basement roof with the support system. This construction method can effectively use the stiffness of the main structure to provide horizontal force for the deep foundation pit in a narrow space, enhance the support ability and ensure the building safety of the surrounding old residential areas. It provides a good reference for the semi-reverse construction technology of basement roof and support system in the future. Through the research on the semi reverse construction of deep foundation pit, this paper summarizes the innovative technical essentials of semi reverse construction, expounds its technological principles and operating points, solves the technical problems of difficult combination of forward and reverse construction and improves the good economic benefits for the semi reverse construction technology.展开更多
