Subway tunnel deformation monitoring based on 3D laser scanning technology

Year: 2025

Type: article

Abstract: As urban infrastructure, particularly subway systems, gets more intricate, it becomes crucial to prioritise the upkeep of its structural stability and safety. To guarantee the safety, structural stability, and operational effectiveness of subway tunnels, the study proposes using the TunnelScanPro framework, which uses 3D laser scanning technology to monitor and analyse changes in the design and form of subway tunnels over time. This study uses a three-dimensional laser scanning technology to monitor changes in the geometries of subway tunnels. More specifically, the study focuses on using visual information to evaluate the structural integrity and safety of the tunnels. The paper aims to use 3D laser scanning technology to offer insights and methods that may be used in practical situations to help with proactive monitoring and repair of subway tunnels. The TunnelScanPro framework detected deformations in subway tunnels with 95% accuracy. Safety improved 40% and high-risk deformations decreased significantly, according to the study.
