ABSTRACT
3D rapid modeling technology of segment and tunnel is the foundation of tunnel construction visualization and Information management. With the in-depth application of BIM (Building Information Modeling) technology in tunnel construction, segment and tunnel 3D rapid Modeling technology have important application value for tunnel construction Information management. With the gradual in-depth application of BIM (Building Information Modeling) technology in the field of domestic architecture, this technology has important application value. In this paper, parameterized modeling of shield tunnel was studied by Dynamo platform, and 3d tunnel modeling program is constructed by visual programming language, which can be used for rapid modeling of the tunnel. The tunnel model can be generated by directly inputting parameters, and parameterized modeling of the tunnel can be realized. The operability and practicability of the system are verified by the engineering practice of a sample section of the Beijing subway.
