摘要:Qingdao Metro Line 3 is the first subway line in Shandong province, some tunnels need to cross water-rich sandy layers. At the time of passing through the water-rich sandy layers, how to maximum the deformation characteristics of the tunnel during excavation becomes the critical problem of the design and construction. This paper studies Qingdao Metro Line 3, directs at water-rich sand layer section YK16+382, with the use of on-site monitoring and measuring instruments, analyses the characteristics of ground deformation of the cross section. And we calculated the deformation by Flac3D numerical simulation in YK16+382 cross section, studied the arch and surface subsidence and convergence deformadon variation of convergence. Finally compare site monitoring measurement with numerical computational results and then we can get the convergence of arch and surface subsidence and convergence deformadon, provide theoretical guidance for the actual construction.
