| Abstract: | Housing density（most of them are raft、expanded foundation） is very big in the overlapped section of LaoShai interval of Shenzhen Metro Line,the minimum space between the tunnel is only 1.6m,and 4m between the tunnel and the housing basement.To ensure the safe use of surface housing,establish the surface adjacent building settlement control standards in the LaoShai interval,optimize the parameters of Shield Tunnel Construction according to the results,and set reinforcement program.Through the application of the program,get a Effective control of the overlapped shield tunnel construction on the adjacent surface structures.Research provides the theoretical support for the smooth construction of overlapped tunnel in the LaoShai interval and safety use of surface adjacent buildings,and also provide a reference for similar construction. |
