Abstract: This paper has taken the BIM model of large-diameter shield tunnel as an example to explore the modeling methods and steps of ring shield tunnel and has solved the difficulties during the modelling process of the building. Based on the analysis of the structural characteristics of the large-diameter shield tunnel, the software which are suitable for the large-diameter shield tunnel BIM model creation have been selected, and the specific implementation steps of the model are described in detail. Through research and demonstration, the BIM model of large-diameter shield tunnel is accurately modeled based on the design data.
