摘要:IFC标准是定义和描述建筑产品信息模型的国际通用标准，发展至今，IFC在建筑工程领域已经得到了广泛的应用，但由于标准还在逐步完善，其在道路、桥梁、隧道等线状工程中的应用仍相对较少，使得相关领域的数据共享受阻。本文介绍了基于IFC4x1 schema描述桥梁上部结构构件空间位置和几何形状的原则，提出了对IFC模型的相关信息进行提取、处理并最终映射到桥梁计算模型的方法，并基于开源库XbimEssentials开发了IFC模型向桥梁计算软件MIDAS Civil模型进行转换的程序原型。
Abstract: The Industry Foundation Class (IFC) is an international standard which describes building and construction industry data. IFC has been widely developed and applied in architecture fields, but has relatively less research on alignment-based infrastructure projects such as roads, bridges and tunnels, which hinders the data sharing in these areas. In this paper, methodologies to describe the spatial location, geometry and other attributes of bridge superstructures based on IFC4x1 schema are introduced. This paper also presents an approach to map data from IFC to MIDAS Civil. Additionally, a prototype is developed based on the open-source library XbimEssentials to verify the approach presented.
