在规模大、构件布置复杂的钢桁加劲梁桥设计和施工过程中,平面图纸的抽象性和效果图视角的局限性对决策者是一种限制.结合坝陵河特大钢桁梁桥工程,以Autodesk CAD为平台对其建立三维精细模型,对桁架各杆件的连接部位进行预拼装,对杆件和节点设计进行对接校核,经数据转换直接生成可视化的虚拟现实模型.建立的坝陵河特大钢桁桥梁空间模型可以为决策者提供可视化的分析平台,为科学决策提供技术支持.
Abstract：The design and construction of the stiffening steel truss bridge is a complex and large-scale professional program.The plans Abstraction and the view angle weakness of the design sketch will become limitations to the owners and the decision makers.Based on the project of large stiffening steel truss girders on Baling River,a three-dimensional fine model is established for it by means of Autodesk CAD.By the model,the joint parts of member bars are pre-assembled,and the docking of member bar and joint design is checked,then the data conversion of this model directly generates a virtual visualized model.The visualized fine model of Baling River Bridge could provide a visual analysis platform for decision makers,and also offer the technical guarantee and support for sensible decision making.
