摘要
当前正处于实现“两个一百年”奋斗目标的历史交汇期间,作为现代交通运输基础设施之一的高速公路建设需求与日俱增。云南地区山川河流密布,隧道占比显著,传统的隧道设计方式已经无法满足当今发展的需要,引入BIM技术的隧道设计越来越成为主流设计方向。由于高速公路隧道几何上具有平面带状、空间起伏的特征,且隧道结构上具有同一断面层次分明、不同断面千差万别的特征,在隧道设计上直接引进房建BIM技术路线将造成水土不服、无法落地的问题。本文采用Revit+Dynamo的技术路线实现了长螺旋隧道真三维模型创建,为高速公路隧道BIM建模积累了宝贵的经验。
As one of the modern transportation infrastructures,the demand of expressway construction keeps growing since China is now standing at a historical juncture of achieving the two centenaries′goals.The ratio of tunnel in expressway construction is much higher in Yunnan province due to mountainous topography;traditional design method cannot satisfy the demands nowadays,therefore,BIM technology is introduced since it becomes a main direction in project design.Since tunnel in expressway looks like a flat ribbon geometrically,goes up and down spatially,presents cross-section differently,if architectural BIM method is directly applied,it actually doesn’t work and doesn’t acclimatize."Revit+Dynamo"method is used in this article to solve the real 3D modeling of long spiral tunnel,which accumulates experience for future tunnel BIM modeling practice.
