摘　　要：通过对IFC4数据标准框架及存储结构的研究,结合电气化铁路接触网自身的特点,充分考虑数据标准的兼容性及可扩展性,参照传输/配送系统的定义模式,总结接触网系统结构组成及电能配送关系,提出基于IFC4的电气化铁路接触网BIM数据存储标准扩展原则及具体实施方案,分别从实体构件、预定义类型及属性集三个方面对IFC4标准进行扩展,为铁路行业开展多专业、跨平台协同设计,实现信息模型的数据转换与数据共享提供技术支撑。With the study of the IFC4 data standard framework and storage structure and in view of the characteristics of electrified railway overhead contact system,this paper summarizes the structure of the overhead contact system and the relationship of power distribution and proposes BIM data storage standard extension principle and concrete implementations of electrified railway overhead contact system based on IFC4. IFC4 standard is extended in three aspects： entity,enumeration type and property set. As a result,the standard will provide technical support to allow the railway sector to carry out multidiscipline,cross-platform collaborative design and application of information models through data transformation and sharing.
