基于BIM的钢管混凝土系杆拱桥碰撞分析研究

Collision Analysis of Concrete Filled Steel Tube Tied Arch Bridge Based on BIM

以大跨度钢管混凝土系杆拱桥为研究对象,基于BIM的Revit软件,通过添加图元的方式创建三维模型,以便从模型中提取所用的构件信息,提供真实可靠的数据,进行整体三维模型的分析与计算;基于Navisworks软件的碰撞分析技术,显示构件的ID号、位置、图片等信息并实时反馈给参与者,解决了大型复杂工程中的“错、漏、碰、缺”等系列问题。该研究成果可对实际施工过程进行有效的指导。

The long-span concrete filled steel tube(CFST)tied arch bridge is taken as the research object.Based on BIM Revit software,three-dimensional(3D)model is built by adding elements to extract the component information,the real and reliable data are provided and overall 3D model was analyzed and calculated;Based on the collision analysis technology of Navisworks software,the ID number,position,image and other information of the component are displayed and timely fed back to the participants,the series of problems such as‘error,leakage,collision and lack’in large and complex projects are solved.The research results can guide the actual construction process effectively.
