摘要:针对盾构隧道管片建模效率低、精细化程度不足且施工困难等问题，现有研究基于BIM技术对盾构隧道管片进行了参数化建模研究，但参数化自动生成模型的二次开发技术尚不成熟。本文建立通用管片的参数化建模流程，通过Civil3D软件进行盾构区间三维轴线设计，并基于Revit开发Dynamo插件实现区间管片全过程的自动拼装，通过将模型、数据及现场实景照片等信息上传至BIM协同管理平台，实现施工阶段的信息集成管理，为运营期工程维护提供数据支持。通过太原市轨道交通2号线样板区间的工程实践，验证了参数化建模流程的可操作性及二次开发插件的实用性。研究结果表明，隧道管片自动拼装技术能有效提高盾构隧道管片建模速度，实时数据采集与协同管理平台应用可提高项目信息集成化管理水平，为推进BIM技术在隧道管片建模中应用起指导作用。

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.
