基于BIM和本体的大型地下空间精益建造方法研究

Research on Lean Construction Method of Large Underground Spaces Based on BIM and Ontology

自21世纪以来,我国经济飞速发展,城市土地资源的利用趋于饱和,大型地下空间的建造开发成为提高土地利用率的重要途径之一。然而,大型地下空间在开发过程中面临着地质条件复杂、施工难度大、多学科交叉管理等方面的难题。为了实现大型地下空间的高效管理和施工,本研究基于精益建造理念,通过融合BIM和本体技术构建了一个大型地下空间精益建造方法框架。该框架由数据层、知识层、本体层和应用层构成,通过有效整合各类信息并利用本体的查询和语义推理能力,为施工团队提供一个基于知识库和规则系统的决策支持平台,促进大型地下空间精益建造知识的共享。并以三大建筑共享配套设施的大型地下空间工程为案例对该方法进行应用,验证了该框架的可行性和有效性。

Since the 21st century,with the rapid development of economy in our country,the utilization of urban land resources tends to be saturated.The construction and development of large underground spaces has become a significant way to improve the land utilization rate.However,the development process of large underground spaces faces difficulties in terms of complex geological conditions,difficult construction,and multidisciplinary cross management.In order to realize the efficient management and construction of large underground spaces,this study established a framework of lean construction methodology for large underground spaces based on the lean construction concept by integrating BIM and ontology technology,which consists of data layer,knowledge layer,ontology layer and application layer.By effectively integrating various types of information and utilizing the query and semantic reasoning capability of ontology,the framework could provide a decision support platform based on knowledge base and rule system for the construction team and promote the sharing of knowledge for lean construction of large underground spaces.The method was also applied in the case of a large-scale underground space project with three major building shared supporting facilities,which verified the feasibility and effectiveness of the framework and is of great theoretical and practical significance for the efficient development and utilization of large underground spaces.
