Application of 3D Laser Scanning Technology in Quality Inspection of Subway Tunnel Construction
3D laser scanning technology has the advantages of non-contact measurement,high resolution and rich information. It can quickly and comprehensively obtain the high precision holographic point cloud of subway tunnel in the construction stage. In order to study the feasibility of applying 3D laser scanning technology to the quality inspection of subway tunnel construction,this paper makes a deep excavation from the aspects of job preparation,data collection,processing and analysis,proposes a production technology process of 3D laser scanning technology in subway tunnel construction quality inspection,and introduces the key elements of quality inspection and its algorithm in the pro-duction technology process. The practice shows that the high-precision data of subway tunnel can be obtained efficiently through the produc-tion technology process,and the feasibility of 3D laser scanning technology applied to the construction quality inspection of subway tunnels is verified.
