Abstract: With the constant development of bridge design in China, the design methods represented by BIM technology are gradually increasing, and design schemes emerge in endlessly. In order to make the bridge design method based on BIM technology more standard and practical, BIM standard diagram was established according to three standards of BIM technology and the role and connection of the three standards were also intuitively illustrated.Secondly, based on the characteristics and standards of BIM, a standardized technical model of bridge design and construction management based on BIM was established for bridge design and construction stage.Meanwhile, combined with the Honghe Bridge Project of Yanchong Expressway in Hebei Province, the process of BIM model building and application in the design stage was introduced in detail by using Revit software.The applicability of the proposed method is proved by the case study, which provides a standard technical route and practical experience for the development of BIM technology in the field of bridge design in China.

摘要： 随着我国桥梁设计方法的不断发展，以BIM技术为代表的设计方法逐渐增多,其设计方案层出不穷。为使以BIM技术为基础的桥梁设计方法更加标准和实用，首先根据BIM技术的3个标准建立了BIM标准关系图，直观的阐释了3个标准的作用及联系；其次基于BIM的特点和标准针对桥梁设计及施工阶段建立了BIM桥梁设计和施工管理标准化技术模型；同时结合我国河北地区延崇高速公路红河大桥项目，利用Revit软件详细介绍了BIM在设计阶段中的模型建立过程及应用过程。经实践证明了该方法的适用性，为BIM技术在我国桥梁设计领域提供了标准技术路线和实践经验。
