基于Revit+Dynamo的特长隧道可视化

Visualization of long tunnel based on Revit+Dynamo

针对隧道工程现有建模技术精确度低、信息共享不足及工作量大等问题,提出了新的隧道结构和地质模型参数化建模方法。通过深度的精细化建模,高度还原隧道工程图纸,实现隧道结构细节的可视化。以鹤伊高速峰岩山特长隧道工程为依托,采用Dynamo软件对Revit软件进行二次开发辅助模型建立,根据特长隧道独有的建模特点,编写一种特长隧道参数化建模程序。研究表明,将此建模方法应用在构建峰岩山特长隧道BIM模型中,实现了地质模型和隧道结构模型建立。相较于仅利用传统Revit建模方法,该方法有效提高了建模效率,优化了施工进度。

This paper attempts to address a series of serious problems affecting work efficiency,such as low accuracy,insufficient information sharing,and large workload under existing modeling techniques in tunnel engineering,and proposes a new parameterized modeling method for tunnel structure models and geological models.The study works by deeply refining modeling and highly reproducing tunnel engineering drawings to achieve the visualization of tunnel structural details;based on the Heyi Expressway Fengyanshan Extra Long Tunnel Project,using Dynamo software for the secondary development of Revit software;and developing a parametric modeling program of the extra long tunnels according to the unique modeling characteristics of extra long tunnels.The results show that the application of this modeling method in the construction of the BIM model of Fengyanshan Extra Long Tunnel enables the establishment of geological model and tunnel structure model.Compared to the traditional Revit modeling methods used only,this method effectively improves modeling efficiency and optimizes construction progress.
