Research on Optimization of Excavation Methods for Large Section Tunnel of Metro Transition Line |
| |
| Abstract: | Taking the tunnel in transmission line after Ludancun Station of Metro Line 9 in Shenzhen for example, the numerical simulation analysis method is adopted to perform numerical simulation of tunnel construction process of big span metro transmission line. For section E, the double side drift method and CRD method are adopted to analyze the internal force of lining and influence of deformation; the excavation sequence by CRD method is discussed and optimization suggestions for tunnel construction methods and excavation sequences are put forward. |
