Construction Monitoring Technology Analysis for Railway Tunnel

Abstract:

Based on the railway tunnel engineering, the research on comprehensive technological for the monitoring of tunnel construction is performed. It is shown that the deformation of wall rock would mainly suffer the comprehensive influence of multiple factors like type of the wall rock, construction method and supporting measures, size of the excavated section, etc. through the monitoring of the crown settlement, clearance convergence and ground settlement. The wall rock will be stable within 20d and 40d after the tunnel excavation. And the secondary tunnel lining could be constructed. Numerical simulation method was also adopted to analyze the deformation and stress of the wall rock. It is presented that the construction interval shall not be too long for the stability of wall rock. Therefore, the numerical analysis method and site monitoring method could be used together to achieve more comprehensive and reliable monitoring of tunnel construction.
