IFC标准扩展方法在公路工程中的应用探究

Research on Application of IFC Standard ExtensionMethod in Highway Engineering

随着建筑信息模型技术的发展与应用,越来越多的数据贯穿于工程的全生命周期,信息化的数据传递与共享不可避免,选择通用的数据格式是必然趋势.研究IFC标准对工程数据的传递与共享发现,已有的IFC标准不能满足对公路路线及监测仪器的标准与传递;在研究了IFC标准的4层架构及功能的基础上,提出了基于新增实体、基于IfcProxy实体及基于属性集的3种扩展思路,其中兼容性最好、可靠度最高及操作最简单的是基于属性集的扩展;通过属性集的扩展方法,实现了路线中心线及监测仪器中监测信息的表达与传递.研究成果在川九路的边坡监测试点工点中应用,实现了公路数据、监测仪器与监测数据的共享与传递.

With the development and application of BIM technology,more and more data will penetrate the whole life cycle of the project,and the transmission and sharing of information-based data is inevitable.It is an inevitable trend to choose a common data format.The study of the transmission of engineering data by IFC standards finds that the existing of IFC standards cannot meet the requirements and transmission of highway routes and monitoring instruments.On the basis of studying the four-layer structure and functions of the IFC standard,three expansion ideas are proposed based on newly added entities,on IfcProxy entities as well as on attributes,among which the most compatible,the most reliable and the easiest to operate is the expansion based on the attribute set.Through the expansion method based on the attribute set,the expression and transmission of the monitoring information from the route center line and the monitoring instruments are realized.The research results are applied in the slope monitoring pilot site of Chuanjiu Road,which helps realize the sharing and transmission of road data,monitoring instruments and monitoring data.
