Feasibility Study of Self-propelled and Advanced Pipe Shed Based on Fault Zone Monitoring
Based on the fault fracture zone section of Yantian tunnel in Yichun-Suichuan highway,the vault subsidence and horizontal convergence of Yantian tunnel are monitored,through the analysis of field monitoring data,the feasibility of the self-propelled and advanced pipe shed in the fracture zone of Yantian tunnel is verified.The results show that:the self-propelled and advanced pipe shed support scheme can significantly control the tunnel deformation when the tunnel passes through the fault fracture zone,reduce the possibility of collapse and other disasters,and ensure the construction safety;The self-propelled and advanced pipe shed gives full play to the role of stabilizing the face of the hand and strengthening the stratum,and greatly shortens the construction period and saves the cost.Moreover,the construction safety is further guaranteed by adopting the self-propelled and advanced pipe shed combined with the measures of shortening the advance length.
