摘　　要：互通式立交方案不仅会影响路网交通流的转换效率,还会影响行车安全、工程造价。提出将BIM技术应用到枢纽互通式立交方案设计中,详细叙述了BIM技术的优势以及BIM技术在互通式立交方案中的设计方法。利用BIM技术建立了互通三维模型,在真三维环境中进行互通方案比选,并对推荐方案进行通行能力分析、三维视距检查。总结了山区高速公路地形条件复杂、隧道进出口与互通间距较小时互通方案布设的要点,供同类项目参考。The interchange scheme can not only affect the efficiency of traffic flow conversion in the road network,but also affect driving safety and project cost.In the paper,BIM technology is proposed to be applied in the design of hub interchange schemes,and the advantages of BIM technology and its design methods in interchange schemes are introduced in detail.By means of BIM technology,a three-dimensional model of interchange is established,and interchange schemes are compared in a real three-dimensional environment.The recommended schemes are verified in terms of traffic capacity and three-dimensional sight distance.The key points of the layout of the interchange plan for mountainous highways with complex terrain conditions and small spacing between tunnel portals and interchanges are concluded,which is expected to provide some reference by similar projects.
