摘要
为提高基坑工程各参与主体之间信息交流和共享的效率和质量,建立基于IFC标准的基坑围护结构信息模型作为信息交流的基础和核心。首先,研究基于IFC的基坑围护结构信息模型的框架;然后,扩展IFC标准中关于基坑围护结构的描述实体,并基于此建立基坑围护结构建模方法;最后,对建模软件二次开发形成基坑建模插件,并应用于某地铁车站基坑工程中,验证该方法的可行性。基于统一的IFC数据标准建立的基坑围护结构信息模型可以实现基坑围护结构模型建模的自动化,可应用于基坑工程和岩土工程信息化管理。
The industry foundation classes （IFC ） -based information model of retaining structure of foundation pit is built as the basis and core to improve the quality and efficiency of information communication and sharing among subjects of foundation pit projects. Firstly,the framework of IFC-based information model of retaining structure is studied; and then a series of IFC entities of enclosure structure are extended ; and a method of retaining structure modeling is established according to the extended IFC standards. Finally,the Revit plug-in of retaining structures is generated by secondary development of modeling software; and the feasibility of the above-mentioned method is verified by application to foundation pit of a metro station. The automated modeling of retaining structure of foundation pit can be realized according to unified IFC data standards,which can apply to foundation pit and rock and soil projects in the future.
