摘要
为解决山地轨道交通隧道在BIM建模中存在的隧道线路偏差大、隧道构件复杂繁多、属性添加效率低以及呈现效果单一等问题,提出一种基于Revit+Dynamo+Excel及EVS软件的山地轨道交通隧道Geo-BIM建模方法。结合隧道线性工程特点,对Revit内置Dynamo插件二次开发,实现隧道快速精准的参数化建模和批量定义属性参数。提出基于EVS软件建立隧道三维地质体模型的方法,制定地层建模和岩性建模的实现方式和标准流程,结合隧道BIM模型全面实现隧道建设过程中的可视化。依托施家山隧道项目,基于Cesium框架实现了BIM模型、GIS地表和地质体三维模型的集成,实现三维可视化模型与模型属性、数据信息等可交互式操作。实践表明,Geo-BIM建模方法可以快速地对隧道BIM模型及其三维地质模型进行建模,通过集成后的模型信息之间能够表现出很好的交互效果,具有良好的工程应用价值。
In order to solve the problems in the BIM modeling of mountain rail transit tunnels,such as large deviation of tunnel lines,complex tunnel components,low attribute addition efficiency and single presentation effect,this paper presents a mountain rail transit tunnel Geo-BIM modeling method based on Revit+Dynamo+Excel and EVS software.Combined with the characteristics of tunnel linear engineering,the secondary development of Revit's built-in Dynamo plug-in enables fast and accurate parametric modeling of tunnels and batch definition of attribute parameters.This paper proposes a method for establishing a three-dimensional geological body model of a tunnel based on EVS software,and formulates the realization method and standard process of stratigraphic modeling and lithology modeling.Combined with the tunnel BIM model,the visualization of the tunnel construction process is fully realized.Relying on the SHIJIASHAN Tunnel Project,the integration of the BIM model,the GIS surface and the 3D model of the geological body is realized based on the Cesium framework,and the 3D visualization model can be interactively operated with model attributes and data information.Practice shows that the Geo-BIM modeling method can quickly establish the tunnel BIM model and its 3D geological model,and the integrated model information shows a good interaction effect,which has good engineering application value.
