摘　　要：枢纽互通作为高速公路改扩建重要的节点控制工程,是实现快速交通转换、充分发挥路网功能的重要保证。文章以南京至宣城高速公路机场枢纽改扩建为例,探讨双主线枢纽互通在多重外部制约下进行改扩建的方案研究思路,可为同类枢纽方案设计提供参考。As an important node control engineering for expressway reconstruction and expansion,hub interchange is an important guarantee to realize rapid transportation conversion and give full play to the function of road network.Taking the reconstruction and expansion of the airport hub on Nanjing-Xuancheng Expressway as an example,this paper discusses the research ideas for the reconstruction and expansion of the double main line hub interchange under multiple external constraints,which can provide reference for the design of similar hub schemes.

关 键 词：双主线 枢纽互通 改扩建方案
