Abstract: The results of the study show that the automatic splicing of tunnel pipes can effectively improve the modeling speed of the tunnel tube. The real-time data acquisition and collaborative management platform application can improve the management level of the project information, and apply the application of BIM technology in the modeling of tunnel pipes. Aiming at the problems of low modeling efficiency, insufficient fineness and construction difficulty of shield tunnel segments, some researchers have carried out parametric modeling research on shield tunnel segments based on BIM technology, but the second development technology of the automatic generation model is immaturity. In this paper, the parametric modeling process of the general tube is established, and the 3d axis design of the shield is carried out through the "Civil 3d" software, and the automatic assembly of the whole process of the interval pipe is implemented based on the dynamo, the Revit plug-in. By uploading information such as model, data and scene photos to the BIM collaborative management platform, the information integration management of the construction stage is realized, and the data support is provided for the maintenance of the operation period. Through the engineering practice of the line sample interval of the Taiyuan city subway line 2, the operability of the parametric modeling process and the practicability of secondary development plug-in are proved.
