Abstract：Research purposes: In terms of BIM design for railway stations, commercial BIM software generally has some problems, such as insufficient station design function, more repetitive operations, insufficient precision of model, unable to accurately express local details, which greatly restricts the application of BIM in railway station design. By analyzing the characteristics of railway station BIM design, the paper discusses the key technologies of railway station BIM design system from system architecture, function design, parametric modeling, attribute binding and model integration, in order to solve the shortcomings of commercial BIM software and realize the efficient BIM design of railway station. Research conclusions: (1) According to the characteristics of BIM design of station, based on the in-depth study of BIM modeling principle, the method of BIM modeling of station is proposed. (2) By adopting the idea of hierarchical architecture, the BIM design system of railway station is developed on Bentley MicroStation platform, and the parametric modeling of BIM model of railway station is realized. (3) The application in the project shows that the system is not only accurate in calculation, but also stable, reliable, simple and easy to use, which can greatly improve the efficiency of railway station BIM design.
