水工隧洞BIM建模关键点的探索

Key Points of BIM Modeling for Hydraulic Tunnels

水利水电工程中水工隧洞的BIM设计具有其自身的特殊性,常用的Civil 3D无法完全满足建模需求。力求从完全使用Revit创建模型出发,探索模型创建过程中的关键点,如隧洞断面参数化、三维建模方式、主支洞交叉口模型等。同时总结建模经验,使用二次开发技术内化建模流程,实现自动参数化水工隧洞建模。

The BIM design of hydraulic tunnel in water conservancy and hydropower projects has its own distinctive features,and the commonly used Civil 3D cannot fully meet its modeling requirements.By using the Revit,efforts were made to explore key points in the process of model creation,such as tunnel section parameterization,3D modeling method,main and branch tunnel intersection model,etc.This paper also summarized modeling experience,used secondary development technology to internalize the modeling process,so as to realize automatic parametric hydraulic tunnel modeling.
