Abstract:Research purposes: The ridge section of Wushaoling tunnel crosses the compressed zone of a regional fault with fracture weak surrounding rock and large compressed deformation, so it is necessary to seek feasible control technology for the purpose of guaranteeing the security of tunnel construction.
Research results: Through doing research on control technology for deformation of the ridge section of Wushaoling tunnel, the relative measures can be taken for successful control of the tunnel deformation in construction, including choice of reasonable dross section shape, remaining deformation amount for the tunnel in advance, multi-supporting, enhancing the rigidity of the flexible lining structure and adopting short benched method with rapid excavation, rapid supporting and timely lining.
