Research and Application of Parametric Modeling of Shield Tunnel Based on BIM Technology
In order to solve the problem of low 3D modeling efficiency of complex shield tunnel projects,a parame-terized modeling method and related technical path was proposed based on BIM technology in this paper.The 3D model of shield tunnel was built by Revit software and Dynamo visual programming function to optimize the modeling steps.The project of Huanghai Road station-Fuxing Road station of Wuhan Rail Transit Line 12(Jiangbei Section)is taken as an example to make research.The results show that:1)The functional relationship of model component size can be established to improve modeling efficiency based on BIM technology and parametric modeling path;2)The 3D model of shield tunnel established by Revit software and Dynamo has high precision and be appliable for 3D vi-sualization and subsequent numerical simulation of the projects.Through the above methods and technical paths,the parametric modeling and engineering application of shield tunnel are realized,which can provide reference for similar shield engineering modeling and related applications.
