Abstract: AEC industry has experienced from paper drawings to 2D CAD drawing and component-based BIM. The usage of information technology improves the efficiency and quality of construction projects, and shortens the construction cycle. However, the traditional way of construction information integration and sharing is based on BIM model base and relation-database. It is difficult to realize the flexible and dynamic transformation of user-centric information, and also greatly increases the capacity of information, resulting in the speed of system response slow and inefficient. In this paper, through the analysis to the shift of information integration mechanism in the construction and engineering industry, it proposes the ontology-based building information model integration mechanism. On the basis of the construction information classification, the paper puts forward the mapping mechanism between building ontology and building information model. Besides, taking pipeline leakage in the stage of construction maintenance as an example, through the establishment and reasoning of the architecture ontology, the paper uses the CPN Tools and Jena to realize the positioning to the leakage section, determine the leakage causes and finalize the maintenance solutions.

摘要： 建筑行业经历了由纸质的图纸到二维的CAD制图，再到以构件为基础的BIM建筑信息模型的变迁，信息化革新提高了建筑项目的效率和质量，并缩短了建筑施工周期。然而，当前建筑信息集成的方式主要基于BIM模型库和关系型数据库，无法实现柔性地基于用户需求的信息组织与传递，极大地增加了信息传递中的承载量，造成系统响应速度慢和效率低下。通过分析建筑工程信息集成与交互的现状，提出基于本体的建筑信息组织与交互模型，并建立建筑信息对本体的映射机制和推理方式。最后以建筑项目运维阶段的管网漏水为实例，分别使用CPN Tools和Jena工具建立本体构架和推理规则，实现漏水区段的定位、关联原因分析及解决方案确认。
