基于三维实景模型公路桥梁BIM正向设计研究

Research on BIM Forward Design of Highway Bridges Based on 3D Reality Model

摘要:

采用Midas CIM桥梁三维正向设计软件，依托濮阳至聊城高速公路卫城枢纽主线跨线桥工程，基于三维实景模型开展节点桥梁BIM正向设计。将三维模型输出的钢箱梁关键指标与传统二维设计模式输出的结果进行对比分析，结果表明三维正向设计结果可靠，可实现设计阶段BIM模型向施工阶段数字化交付。

Abstract:

The BIM forward design of node bridge is carried out by using Midas CIM bridge 3D forward design software, relying on the main line overpass project from Puyang to Liaocheng Expressway Weicheng Hub, and based on 3D reality model. The key indexes of steel box girder output by 3D model are analyzed and compared with the results output by the traditional 2D design model. The result shows that the result of 3D forward design is reliable and the digital delivery of the BIM model in the design stage to the construction stage can be realized.
