基于BIM的城市景观桥梁深化设计方法

城市景观桥梁具有外型美观、线条独特、造型个性化等突出特点。针对上述特点，在桥梁深化设计阶段引入 BIM 技术和精细化管理理论，并采用基于 BIM 的多软件协同作业平台与基于 BIM 和有限元分析联合深化设计方案，提出一种基 于 BIM 技术的全方位城市景观桥梁联合深化设计管理新方法，并以长白山建封路大桥及引线工程典型城市景观桥为例，介 绍基于 Revit 和 Dynamo 的城市景观桥梁参数化建模方法和具体应用。结果表明:在三维可视化设计和工程量统计等方面均 表现了上述管理方法的精准和高效，基于 BIM 和有限元分析联合深化设计为城市景观桥梁深化设计提供了新思路。

BIM-Based Urban Landscape Bridge Detailed Design Method

The urban landscape bridge has outstanding features such as beautiful appearance，unique lines and individualized shape. In view of above characteristics，BIM technology and refined management theory are introduced in the bridge detailed design stage， a multi-software collaborative operation platform based on BIM and a detailed design scheme based on BIM and finite element analysis are adopted，thus a new method of comprehensive urban landscape bridge detailed design management based on BIM technology is proposed . Taking the typical urban landscape Changbaishan Jianfeng Road Bridge and its lead engineering as an example，the parametric modeling method and specific application of urban landscape bridge based on Revit and Dynamo are introduced. The results show that the above-mentioned management methods are accurate and efficient in terms of 3D visualization design and engineering quantity statistics. The combination of BIM and finite element analysis provides a new idea for detailed design of the urban landscape bridge.
