摘　　要：IFC(Industry Foundation Classes)标准是建筑信息模型BIM的开放式数据格式,它使用空间结构的方式来组织和管理建筑模型信息,使用EXPRESS语言来描述建筑信息。IFC标准包含众多实体,实体之间关系复杂,逻辑层次繁多,对建筑信息的标准化表达和结构化管理,是IFC标准实施的关键。研究分析IFC标准的空间结构组成及对应的IFC中性文件,利用Java插件解析IFC文件。深入探讨使用Java语言编程来读取IFC模型的空间结构组成信息和与其连接的建筑构件信息的方法,并通过具体的建筑工程实例对解析方法进行验证。IFC standard defines the data format of BIM which organizes and manages building modeling information by using spatial structure,and describes building information by EXPRESS language.The IFC standard contains numerous entities with complex relationships and multiplied logical levels.Therefore,the standardization and structured management of the construction information is the key to the implementation of IFC standards.This paper analyses the spatial structure of the IFC standard and the corresponding IFC neutral file,resolves the IFC file with Java plug-in,and explores the spatial structure of the IFC model and the building components by using Java.Finally,this method has been evaluated by a detailed constructional engineering project.
