Application of 3D Laser Scanning Technology in Convergence Deformation Monitoring of Subway Tunnels
Abstract：Subway tunnel convergence monitoring is an important engineering task related to safety. Introducing 3D laser scanning technology into subway tunnel convergence monitoring, using the German Z+F IMAGER 5010C 3D laser scanner to obtain point cloud data of the tunnel, pre-processing the data with Z+F LaserControl software, and post-processing the data with 3DReshaper software. The results of data processing can effectively reflect the convergence deformation of the tunnel and meet the requirements of monitoring accuracy, significantly improving the efficiency and accuracy of cross-section measurement.
