水利工程视角下的BIM与GIS数据融合研究

Research on integration of BIM and GIS data for water conservancy projects

为进一步推进BIM与GIS技术在水利工程实践中的应用,提高水利工程建设信息化水平,研究BIM与GIS技术协同中的数据融合问题。从建模语言、几何表达、语义信息等方面,介绍基于数据格式转换、标准扩展和本体技术集成的3种BIM与GIS数据融合方法,探讨并比较3种数据融合方法在水利工程项目中的应用场景,分析BIM与GIS数据融合在水利工程全生命周期各阶段的应用内容,并以泰州引江河案例为例,对相关技术方法进行实证应用。研究表明:BIM与GIS数据融合是水利工程领域新数据标准建立的重要基础与途径,对提高水利工程项目全生命周期管理及信息化水平具有重要意义。

In order to promote application of BIM and GIS technologies in water conservancy projects,and to elevate its informatization level,this paper explores the data integrated issues that arise in harmonization of BIM and GIS technologies.Three methods of BIM and GIS data integration are introduced based on data format conversion,standard extension,and ontology technology integration,from the aspects of modeling language,geometric expression and semantic information.Furthermore,this paper investigates and compares application scenarios of these three data integration methods in water conservancy projects.Additionally,it analyzes the application of BIM and GIS data integration throughout various stages of the entire project lifecycle.The relevant technological methods are tested empirically by taking the Taizhou Yinjiang River project as a case,and the result shows that BIM and GIS data integration forms a critical foundation and pathway for establishing novel data standards in the field of water conservancy projects,thus substantially contributing to the enhancement of project lifecycle management and informatization.
