Research On Information Modeling Standard Of Metro Interval Construction Based On CBIMS Framework

With the improvement of BIM technology in the application of housing construction projects,it is constantly trying to combine BIM technology with metro construction,using information technology to improve its management efficiency and breaking the previous management model in China.Establishing the corresponding BIM standard is the primary problem in the application of BIM technology in metro engineering.Only by establishing a unified and effective BIM application standard can the rapid popularization of BIM technology be promoted and the efficiency of BIM application be improved.This article takes the related theories of civil engineering informatics,CBIMS framework,BIM as the theoretical basis,and combines informatics theory to analyze the symbols and laws in information transmission.According to the characteristics of metro construction,the information requirements of metro construction interval construction are described from the perspective of the life cycle of the metro construction and the system,and the information requirement table is obtained.In-depth exploration of the CBIMS framework in the construction process of metro applications,and deepening from the technical specifications and application guidance.Combined with the extended CBIMS framework,the classification and coding system for metro construction process and the information representation under different model fineness are deeply discussed,and the storage specification of the file is defined.The analysis of metro construction process standards based on BIM technology is consistent with the trend of civil engineering informationization and has certain theoretical significance.According to the engineering case of Xiamen Metro Line 3 crossing the sea,the BIM standard was applied to the shield method and the mining method used in the construction of the metro project.Based on the standard system,the description of component separation,classification and coding system and model fineness is mainly performed.The actual shield segment is used as an example for modeling application.Studies have shown that the shield method and the mining method technology standards established in this paper have application value and can be widely adopted for metro construction.The research of the paper has practical significance and application value.The application of BIM standards in the construction process of metro projects has a strong research significance.The establishment of relevant standards can effectively improve the management efficiency.
