Tunnel Deformation Monitoring Based On the Terrestrial Laser Scanning Technology

LI Jian  
The integrated deformation analysis of Subway tunnel based on TLS was studied in this paper,and to simplify the point cloud by the method of point cloud segmentation based on vector variance of points was proposed,and then building the subway tunnel model using the simplified point cloud.That constructing the three-dimensional model of subway tunnel is not only improve the accuracy of but also reflect the deformation trend of the integrated tunnel.And the method proposed in this paper was tested by Number 1 subway tunnel of Tianjin,and compared the results with the fiber optical displacement sensor approach,the final result showed that the accuracy of TLS was below 4 mm,and it could meet the need of the deformation monitoring of subway tunnel.
