基于BIM技术的公路线形三维可视化设计

3D visual design of highway alignment based on BIM technology

针对当前公路线形二维设计存在的问题,结合我国某二级公路工程,利用公路工程设计BIM系统,对其公路线形三维设计展开研究,梳理总结出一套完整的公路线形三维建模设计流程,提出基于该系统的公路线形三维可视化设计技术方案。结果表明,与传统的二维设计方法相比,基于BIM技术的三维设计方法能够体现设计意图、快速完成方案比选、自动出图,可为项目决策提供可靠依据。

Aiming at the problems existing in the current highway alignment 2D design,combining with a secondary highway project in China,the 3D highway alignment design is studied by using the BIM system of highway engineering design,and a complete 3D highway alignment modeling and design process is sorted out and summarized.A technical scheme of 3D visualization design of highway alignment based on this system is proposed.The results show that compared with the traditional 2D design method,the 3D design method based on BIM technology can reflect the design intent,quickly complete scheme comparison and automatic drawing,and provide a reliable basis for project decision.
