Abstract:

The 3D information model built by BIM can provide an information circulation platform for road engineering design. It has the advantages of promoting the communication convenience, reducing the design error rate and improving the engineering quality. It can run through the whole life cycle of the project and has been widely used. By introducing the typical characteristics of BIM, the function realization of BIM Technology in road engineering design stage is described. The cost calculation and automatic output function of BIM technical engineering quantity are summarized. The modeling function of BIM technology road engineering design is discussed. The applications of 3D route design, subgrade and pavement modeling, and fast road overall modeling are studied in detail. Finally, the complete flow of road engineering design based on PowerCivil software is obtained, and can provide the reference for the further promotion of BIM technology in the road engineering design.
