摘　　要：采用三维可视化技术,实现了公路隧道的三维建模与可视化表达。详细论述了地形、隧道构造物以及公路附属设施的三维模型建立方法,探讨了三维对象模型与地形模型的匹配问题,在此基础上分析了公路隧道三维可视化过程。通过具体事例表明该方法能将虚拟的工程面貌与三维场景形象直观的表现出来,具有很好的应用性。Using 3D visualization technique, 3D models and visual representation of highway tunnels are realized in this paper. 3D modeling methods of terrain, highway tunnel structures and road attached establishments are presented in detail. Taking into account the matching relation between 3D objects with terrain model, the visualization processes of highway tunnels are analyzed. 3D visualization of highway tunnels is realized and the virtual engineering is visually described. Practical application shows that this approach has good adaptability and provides a new supplementary means for 3D visual design of highway tunnels.
