Canal Reach Deformation Monitoring Technology Based on Terrestrial LIDAR Scanning Technology
Canal reach soil of the south to north water transfer project has a certain expansibility. Concrete lining plates is puring on the soil. After about half a year of water immersion test, a certain plastic deformation has happened on the lining plates because of the expansion in the soil. In order to monitoring the whole lining plates deformation pre and post water immersion test, point clouds is collected by Terrestrial LIDAR and total station. After constructing of triangular mesh and endowing the specific color, the two group of mesh can be overlapping displayed. Deformation area can be found easily by color distortion on superposition chart. And then deformation tendency is concluded.
