Abstract:Due to the high construction difficulty and short construction period of earthwork engineering, it is necessary to apply the digitizing technology to achieve the need of cost reduction and efficiency improvement. Taking an actual project as an example, the application of UAV oblique photography technology in road subgrade earthwork engineering is studied. By utilizing UAV to collect the point cloud data comprehensively and quickly and BIM technology to quickly calculate and simulate construction, the goal of rapid excavation and filling of road subgrade earthwork is achieved. Compared with traditional construction methods, the technology has the advantages of sufficient construction preparation, rapid construction, and less labor and equipment investment, which plays an important role in the control of project schedule and cost, and can provide the reference for the construction of similar subgrade earthwork projects.
