Abstract: With the continuous updating of bridge design methods in China, the design methods dominated by BIM technology are also increasing, but the design modes are different. In order to make BIM bridge model design more simple, accurate and information processing more effective, the technical model of BIM bridge design and construction management based on IFC standards was improved firstly, which was based on the IFC standard as the theoretical basis and combined with the technical route of bridge design and construction management in China. Secondly, the bridge BIM model data coding rules were constructed according to the building information model classification standards. Finally, the modeling and deepening design of the project were successfully carried out through Revit software. The research results can provide theoretical support and technical experience for the development of BIM technology in bridge construction in China.

摘要： 随着我国桥梁设计手段不断更新，以BIM技术为主导的设计方式也在逐渐增多，但设计模式各不相同。为使BIM桥梁模型设计更加简便、准确及信息处理更加有效，首先立足于IFC标准为理论基础，结合我国桥梁设计及施工管理的技术路线，改进了基于IFC标准的BIM桥梁设计及施工管理技术模型；其次根据建筑信息模型分类标准构建了桥梁BIM模型信息数据编码规则，最后通过Revit软件对该项目成功进行了建模及深化设计等过程实践。研究成果可为BIM技术在我国桥梁建设中的发展提供理论支持和技术经验。
