摘　　要：为解决机场跑道系统在全生命周期建筑信息模型(BIM)应用中的信息传递和数据交互问题,将工业基础类(IFC)标准在机场跑道系统进行扩展,建立机场道面结构的IFC实体架构,在此基础上创建面向运维应用的刚性道面板实体,并进行几何信息与属性信息的扩展;提出基于IFC的属性信息添加与传递方法,对信息传递过程中的属性信息丢失率进行分析。研究表明:通过建立IFC标准模型,可以实现机场跑道系统的信息传递和数据交互;采用基础模型族扩展法进行机场道面模型传递的属性信息丢失率高达84.21%;采用IFC解析扩展法首次传递可保证信息不丢失,但二次传递信息存在丢失问题;族模型IFC解析扩展法可实现信息首次传递不丢失,二次传递属性信息丢失率低至16.7%,并且采用不同IFC标准版本对模型传递过程中的属性信息丢失率产生较大影响。应用IFC标准进行机场领域扩展具有较高的可行性,所提的信息传递方法可实现机场道面全生命周期信息传递。研究成果可为机场飞行区新IFC实体的扩展提供支持,为机场工程数字化提供技术参考。To address the issues of information transfer and data sharing in the full-life-cycle building information modeling(BIM)application of the airport runway system,the industry foundation classes(IFC)standard was extended to the airport pavement structure.The IFC entity framework of the airport runway system was summarized.Besides,the rigid runway pavement entity considering the operation and maintenance stage was proposed.The graphical information and non-graphical information of the proposed entity were expanded.In addition,an analysis was conducted on the rate of attribute information loss during information model transfer,as well as the most effective way to add and transmit attribute information using the IFC standard.The study shows that the model based on the uniform IFC standard can transfer and share information about airport runway systems effectively.The information loss rate of the family parameter extension method during runway pavement model transfer is as high as 84.21%.The IFC file extension method can ensure the model information integrity during the first transfer process.However,the model information is lost during repeated transfer.A proposed method,combining both the family parameter extension and IFC file parsing,can achieve the model information integrity during the first transfer.In addition,the information loss rate is less than 16.7%during the second transfer.The information loss rate is also influenced by different versions of the IFC standard.It is necessary to extend the IFC entity in the airport domain.As a whole,the proposed information transfer method is appropriate for airport runway lifecycle information management.The research can provide support for the establishment of a new IFC entity in the airfield area,and make a technical reference for digital airport construction.
