Research on Lean Construction Method of Large Underground Spaces Based on BIM and Ontology
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 un-derground 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 vari-ous 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 fa-cilities,which verified the feasibility and effectiveness of the framework and is of great theoretical and practi-cal significance for the efficient development and utilization of large underground spaces.
