Slope Deformation Analysis and Research Based on 3D Laser Scanning Technology

Aiming at the characteristics of traditional monitoring methods of slope deformation, such as low efficiency of single point measurement, limited operation area, time-consuming and laborious and difficulty in analyzing the overall deformation of slope. Taking the high cutting slope of a certain ramp section of suizi expressway as the research object, 3D laser scanning technology was used to scan the slope and obtain 3D point cloud data of the slope in different periods. The original data were pre-processed by point cloud registration, noise reduction, algorithm filtering and so on to obtain a 3D fined model, so as to realize the overall deformation analysis of the slope and the key monitoring of characteristic parts. The results show that 3D laser scanning technology can obtain more comprehensive 3D spatial information of the slope and realize the high efficiency and high precision monitoring of slope deformation, which is of significance for the real-time monitoring of slope deformation and disaster early warning.
