The invention relates to the technical field of three-dimensional models, in particular to a
laser scanning technology-based high slope backfill construction method under
karst landform. Comprising the following steps that S1, construction site data are determined, and the construction data comprise a project range, a digging and filling boundary, a digging area, a filling area and
a site level elevation; s2, performing three-dimensional scanning in the construction site, and establishing a three-dimensional
point cloud model of the construction site; s3, the construction site is calculated according to the three-dimensional
point cloud model, and the excavation amount and the filling amount are obtained; s4,
slope stability evaluation is conducted on the high slope of the construction site, and high slope
construction design is conducted; s5, in the construction process, three-dimensional
point cloud data and material information of materials of the
material storage yard are collected, and a material
database is established for storage; and S6, collecting equipment is designed on the transport vehicle, the loading capacity and the
material type are collected in the loading process, and a transport strategy is generated according to the
material type.
