【摘要】 本文对基于Revit和Dynamo的公路桥梁参数化建模技术进行了研究，通过从构件库建立、程序编制、数据计算到参数化建模的技术路线，实现了公路桥梁下部结构和上部结构的快速建模。首先对参数化建模软件选择及参数化建模流程进行了阐述，其次对现浇梁、预制梁等结构提出了程序编制和数据计算的针对性思路。经实践验证该方法能够有效提高公路桥梁建模效率，为公路桥梁正向设计提供了一种借鉴思路。更多还原

【Abstract】 This paper studies the parametric modeling technology of highway bridge based on Revit and Dynamo. Through the technical route from component library establishment, programming, data calculation to parametric modeling, the rapid modeling of highway bridge substructure and superstructure is realized. Firstly, the selection of parametric modeling software and the process of parametric modeling are described. Secondly, the specific ideas of programming and data calculation are put forward for the structure of cast-in-place beam and precast beam. It is proved by practice that the method can effectively improve the modeling efficiency of highway Bridges and provide a reference for the forward design of highway bridges.更多还原
