| Abstract: | According to the features of massive point clouds by applying 3 D laser scanning technology to subway deformation monitoring,a new method to analyze the tunnel deformation is proposed.Different steps including establishment of reference system,point cloud segmentation,gridding,difference calculation and deformation analysis are elaborated in detail,a subway tunnel being observed is tested and analyzed.The results show that the new tunnel deformation analysis method proposed in this paper can determine the location and size of the tunnel deformation,directly show the detection result and effectively measure the tunnel deformation. |
