摘　　要：以山西东纵高速公路岩头互通式立体交叉方案设计比选为例,研究在复杂地形及多因素控制条件下的一般互通式立体交叉方案设计。设计应综合考虑路网、交通量、主线平纵面指标等因素,在满足通行能力条件下应尽量减小互通规模。根据互通式立体交叉特点及节点功能,提出经济、合理的最优方案,可供类似互通方案的设计提供参考。This paper takes the design and study on Yantou interchange schemes of Dongzong expressway in Shanxi Province as an example,to study the design of general interchange program under the conditions of complex terrain and multi-factor control.The design should take into account the road network,traffic volume,main line longitudinal and level surface indicators and other factors,in order to meet the conditions of capacity should minimize the size of the interchange.According to the characteristics and node functions of the interchange,an economical and reasonable optimal scheme is proposed,which can provide reference for the design of similar interchange schemes.
