Deformation monitoring of highway goaf based on three-dimensional laser scanning
With the rapid development of transportation expressway, different traffic lines must pass through different geological areas. For expressways, when they pass through areas with abundant mineral resources, they may face the instability and destruction of roadbed and pavement of expressways in mining areas caused by mining and goaf subsidence. Because 3D laser scanning technology has the characteristics of non-contact measurement, high spatial resolution and fast scanning speed, it has incomparable technical advantages in highway goaf deformation monitoring. Therefore, this paper mainly studies the application of 3D laser scanning technology in highway goaf deformation monitoring. The acquisition and processing of point cloud data in highway goaf monitoring are discussed in detail, including point cloud data acquisition method, stitching principle and method, point cloud filtering principle and surface reconstruction principle. It is found that the error of deformation monitoring by 3D laser scanning method is small, which indicates that 3D laser scanning technology can accurately and effectively monitor the settlement of linear buildings such as highways.
