摘要
高速公路与城市道路互通立交的常见形态为三路交叉或者四路交叉。而昆明南连接线高速徐家堆立交受到规划选线的影响,立交形态非常特殊。以此为例,从该立交的规划设计及方案选型等系列过程,分析了高速公路与城市道路互通异形立交的设计要点,以期为类似工程提供借鉴。
The common form of interchange between expressway and urban road is 3-way intersection or 4-way intersection.However,Xujiadui interchange of Kunming South connecting line is affected by the planned route selection,and the interchange form is very special.Taking this as an example,from the planning and design of the interchange and the selection of the scheme,this paper analyzes the design points of the interchange between expressway and urban road,in order to provide reference for similar projects.
