Research On Collaborative Design Application Of Subway Comprehensive Pipelines Based On RBAC And BIM

Due to the intricate spatial layout and non-integrated disciplines used for thedesign,the effective and accurate coordination and interaction are scarce during the design process,leading to the poor collaboration and severe cross interference in the conventional 2D model of metro integrated pipelines.In view of the above problems,this study proposed a collaborative design method of subway comprehensive pipelines based on role-based access control(RBAC)and building information model(BIM).What’s more,this method can realize information sharing and control the coordination of data exchanges and activities among different design professionals with the aid of BIM and RBAC.The main contents are as follows:(1)Based on BIM technology,IFC standards and the XML file,it establishes cross Platform the data storage mechanism of multi-disciplinary collaborative design of subway comprehensive pipelines,to improve the data adaptation and exchange ability.The design information model regulations for subway comprehensive pipelines is established to lay the foundation for the multi-disciplinary collaborative design of subway comprehensive pipelines.(2)The interaction requirements of multi-disciplinary collaborative design of subway comprehensive pipelines BIM information on different design stages are studied,and a multi-specialty collaborative design pattern and content of multi-disciplinary collaborative design of subway comprehensive pipelines based on collaborative design platform are built.A multi-disciplinary collaborative design process for subway comprehensive pipelines is established.Collaborative design and delivery of subway comprehensive pipelines are stipulated,and the process of rational organization of collaborative work is carried out.(3)Based on the new cooperative mode and method,the RBAC model of cooperative work is researched,the database construction of cooperative platform is constructed,the specific authority of multi professional collaborative design is designed,and the system architecture of collaborative design of platform is built,the detailed functional modules and interfaces are designed,and the prototype system of the subway comprehensive pipelines cooperative design platform based on RB AC and BIM is developed.Combined with the actual underground rail transit project,the BIM design model and platform proposed in this paper are verified,and the results show that this research could provide reference for the multi-disciplinary collaborative design and implementation of subway comprehensive pipelines in China,which will help improve the efficiency and quality of collaborative design and improve the BIM information technology of the design enterprise and management level.
