Three-Dimensional Geological BIM Modeling Method Based on Shield Construction Simulation

This paper presents a three-dimensional geological Building Information Modeling (BIM) method aimed at addressing safety simulation and rational construction parameter challenges in shield tunneling under varying geological conditions. Incorporating the characteristics of metro shield tunnel modeling, this study utilized both Revit and Dynamo software for modeling. The integration of information on completeness and depth, essential for meeting the requirements of shield tunnel construction, was achieved in the model. This integrated information was then effectively transferred to the finite element simulation model, addressing issues related to communication among participating units and the transmission of information between the BIM model and the finite element model. The research findings demonstrate that the three-dimensional geological BIM model, grounded in shield construction simulation, achieves the automation of shield construction object representation and information updating, thereby enhancing the level of informatization in shield construction.
