Visual Monitoring Technology of the Tunnel 3D Laser Scanning and Engineering Applications

Abstract

Tunnel monitoring and measurement is a very important part of the tunnel construction safety andit is one of the important contents of tunnels on Railway Passenger Dedicated Lines segment acceptance, Its purpose is through the tunnel clearance convergence and settlement observation,to analysis data, optimize tunnel construction and design, and determine a reasonable safety step and support time, protect tunnel construction and operational safety, Although the domestic and foreign on tunnel monitoring measurement work are very seriously, but at present the requirements of monitoring level and information construction are far away. This article based on 3D laser scanning technology, proposed tunnel 3D laser scanning measurement and data visualization technology, through the engineering application and practice, the results show that the technique can be real-time, accurate and comprehensive to get the deformation data of tunnel space,and can analysis and counter-analysis the deformation of tunnel construction, it has greatapplication value of engineering for early warning forecast the risk and guidingtunnel construction.

Information Technology Applications in Construction Safety Assurance

“…An automated blind spot detection tool was presented that determines the equipment blind spots rapidly and in 3D through analysis the point cloud data from a laser scan inside the equipment cab (Teizer et al 2010), see Figure 10. Other application and practice of using point cloud data of equipment were presented and validated in a tunnel deformation monitoring (Wu et al 2013b). Fig.…”

Safety enablers using emerging technologies in construction projects: empirical study in Malaysia

“…To achieve an integrated construction safety 4.0 environment, various safety technologies emerged and developed over the years, such as building information modelling (BIM), unmanned aerial vehicles (UAV), wearable technologies, laser scanning, RFID and many more (Karakhan et al, 2019;Martinez et al, 2020;Wu et al, 2013;Zhou et al, 2013).…”

“…Numerous concerted efforts have been taken to advocate and encourage these construction technologies and the significances of these technologies have been emphasised in the existing literature (Li et al , 2017; Skibniewski and Zavadskas, 2013; Zhou et al , 2015). To achieve an integrated construction safety 4.0 environment, various safety technologies emerged and developed over the years, such as building information modelling (BIM), unmanned aerial vehicles (UAV), wearable technologies, laser scanning, RFID and many more (Karakhan et al , 2019; Martinez et al , 2020; Wu et al , 2013; Zhou et al , 2013).…”

A BHR Composite Network-Based Visualization Method for Deformation Risk Level of Underground Space

“…Tang has shown that the difference evolution arithmetic and visualization toolkit can be used to calculate and evaluate the state of tunnel surrounding rock [ 4 ]. A 3D laser scanning system has also been used to acquire and visualize monitoring data on underground space deformation [ 5 , 6 ]. Chen has studied the browsing modes of the 3D simulation view in monitoring underground construction [ 7 ].…”
