BIM在公路山岭隧道全生命周期中的应用

Application Research of BIM in the Whole Life Cycle of Highway Mountain Tunnel

以云南昆明绕城高速公路杨林隧道为依托工程,结合BIM技术开展了从隧道参数化建模到施工信息管理再到BIM模型与数值模型交互方法的研究。应用Autodesk Revit软件平台,基于Dynamo可视化编程技术,开发了公路山岭隧道参数化建模系列节点包程序,高效地创建了隧道路线模型、隧道衬砌模型、隧道支护模型、地质模型;开发参数信息创建及录入自动化程序,实现隧道工程数据批量化导入BIM模型;基于中间格式文件“.sat”实现Revit与Midas GTS NX之间的模型交互,将建模区段的模型进行施工数值模拟并反馈到模型中。研究成果可为BIM技术在公路山岭隧道以及其他地下带状工程在设计、施工、运维等全生命周期中的应用提供技术参考。

Based on the Yanglin Tunnel of Kunming Expressway in Yunnan Province,combined with BIM technology,the research of tunnel parametric modeling,construction information management and BIM model and numerical model interaction method was carried out.Using Autodesk Revit software platform and based on Dynamo visual programming technology,a series of node packages for parametric modeling of highway mountain tunnel were developed,which effectively created tunnel route model,tunnel lining model,tunnel support model and geological model.Automatic procedures were developed for parameter information creation and input,and mass import of tunnel engineering data into BIM model was realized.The model interaction between Revit and Midas GTS NX was also realized based on the intermediate format file".sat",and the model in the modeling section was simulated and fed back to the model.The research results can provide technical reference for the application of BIM technology in the design,construction,operation and maintenance of the whole life cycle of highway mountain tunnel and other underground belt projects.
