摘　　要：随着城镇化程度越来越高,路网越来越密,在城区增设枢纽互通式立交面临着更多的难题。以成彭高速公路古城枢纽互通为例,根据转向交通量、地形地质条件,结合“三区三线”以及与既有互通的结合情况,提出两个设计方案,并从工程规划、可实施性以及交通功能需求等方面,对互通方案进行比选,为城区高速公路枢纽互通式立交的方案设计提供参考。With the increasing degree of urbanization,the road network is becoming more and more dense,and adding hub interchanges in urban areas is facing more difficulties.Taking the ancient city hub interchange of Chengpeng Expressway as an example,based on the turning traffic volume,terrain and geological conditions,combined with the“three zones and three lines”and the combination with existing interchanges,two design schemes are proposed.From the aspects of engineering planning,feasibility,and traffic function requirements,the interchange schemes are compared and selected to provide reference for the design of urban expressway hub interchange schemes.
