Application Research of BIM Technology in Highway Prefabricated Bridge Scheme Design

At present, the highway bridge scheme requires continuous adjustments and upgrading due to iterative updates of design data and refined investigation of the surrounding environment of the bridge site. This paper upgraded the traditional route design software, developed a GIS-integrated platform, built a three-dimensional environment with design data as the core, and created a bridge scheme model through parametric intelligent design. It also evaluated and optimized the bridge scheme based on the integration of the bridge model and the surrounding environment. The results show that by using BIM technology, the forward design of a bridge scheme based on a three-dimensional environment is realized. This approach automates the scale statistics of bridge construction, the positioning and identification of high piers, and the transmission of design data to downstream professionals for further use. The bridge scheme design based on BIM technology can significantly improve the design efficiency, enhance the intuitiveness of bridge scheme evaluation, and increase the practical value of design data.
