Deformation Monitoring and Data Analysis for Metro Construction with Mining Method in Dalian

Guang Bin Bai, Jie Zhao, Lisheng Liu

Abstract

Based on a subway tunnel construction, the construction method was introduced. The ground subsidence, crown settlement and convergence displacement caused by the cut tunnel are monitored during the tunneling construction and the results of monitoring data for them are analyzed. This technology wells to guide the tunnel-entering construction effectively and avoid the tunnel-entering construction process prone to landslides, thus ensuring the safety of the tunnel construction and will guiding the future construction.
