基于BIM理念的地铁隧道可视化三维设计研究

Research on visualized 3D design of subway tunnel based on BIM concept

随着我国综合国力增强,隧道工程的设计、运营管理朝智能化、一体化发展,严峻的交通现状对地铁隧道工程设计提出了更高的要求。基于BIM理念,利用Civil 3D、Revit、Dynamo三个BIM系列软件,搭建地铁隧道的三维可视化模型。利用Civil 3D线形设计,自动生成隧道断面信息,减轻导入地理信息的重复工作;利用Revit搭建三维模型的信息共享平台,使模型直观可感;利用dynamo可视化编程,降低工程师建模难度,提高工作效率。

With the enhancement of China's comprehensive national strength,the design and operation management of tunnel engineering are developing towards intelligence and integration.The severe traffic situation puts forward higher requirements for the design of subway tunnel engineering.Based on BIM concept,three BIM series software,Civil 3D,Revit and Dynamo,are used to build a three-dimensional visual model of the subway tunnel.Using Civil 3D linear design,tunnel section information is automatically generated to reduce the repetitive work of importing geographic information;Use Revit to build an information sharing platform for 3D models,so that the models are intuitive and perceptible;Dynamo visual programming is used to reduce the difficulty of modeling for engineers and improve work efficiency.
