Abstract :
Virtual reality technology is used to build the three-dimensional scenery model of the tunnel, and on this basis, the advanced safety monitoring of tunnel is implemented. The establishment method of three-dimensional scenery is introduced. First the tunnel´s three-dimensional scanning control network is built and then the integrated tunnel is scanned with Trimble VX Spatial scanners. Lastly we build the tunnel´s three-dimensional model using the obtained point cloud data. Based on the fitting calculation of various cross sections of the tunnel virtual scenery model, the integrated deformation of the tunnel is obtained.
