摘要
互通式立交是高速公路的主要节点,高速公路互通式立交的选型及设置对最大程度地发挥路网功能起着决定性作用。鉴于此,以贵州省三穗至黎平高速公路为例,阐述互通式立体交叉的设计原则、采用的技术标准及设置情况,并对该高速公路上各互通式立交进行优化设计。
Interchange is the main node of expressway. The type selection and setting of expressway interchange play a decisive role for making the network exert its function. Given this, taking Sansui to Liping Expressway in Guizhou as an example, it expounds the design principle, technical standard and setting situation of this interchange. The design schemes of the interchanges on this expressway are op- timized.
