摘要:随着BIM技术在公路工程行业的应用日益增多，对BIM模型的精度要求也越来越高，尤其是桥梁模型构件数量多，精细化建模难度大，效率低。本文针对目前主流的Autodesk Revit建模软件，结合桥梁施工工艺，分析研究了一套预制连续梁桥参数化快速精细建模技术，包含预制T梁、预制空心板梁、预制小箱梁等类型所有预应力砼先简支后连续梁桥的快速精细建模，能够减少人工建模误差，提高建模效率和模型精度，从而为Revit软件预制连续梁桥建模提供参考依据和技术支持，实现了BIM技术在公路工程中应用价值的最大化。

Abstract: With the wide application of BIM technology in highway engineering industry and the higher accuracy requirements of BIM model, especially the bridge model with large number of components and difficult and inefficient modeling. Based on the Autodesk Revit modeling software and actual bridge construction technology, this paper studies a set of prefabricated continuous beam bridge parametric rapid fine modeling technology, including prefabricated T beam, prefabricated hollow slab beam, prefabricated small box girder and other types of all prestressed concrete simply supported continuous beam bridge rapid fine modeling. The method proposed in the paper redues the artificial modeling error and improves the modeling efficiency and accuracy, which provides reference and technical support for the modeling of Revit software prefabricated continuous beam bridge, and finally maximizes the application value of BIM technology in highway engineering industry.
