摘　　要：新庄立交位于南京市中心城区玄武区,现代化国际性人文绿都标志区之一。新庄立交也是南京主城枢纽集疏运系统的重要组成部分,高峰时段拥堵严重。本文依据路网规划、交通量分配预测结果以及现状建设条件等控制因素在理论分析的基础上,综合考虑服务水平及通行能力、工程造价、施工期交通组织等方面合理确定适宜的新庄立交互通改造方案。所述设计思路和研究方法有利于指导同类型城镇密集区互通改造方案设计。Xinzhuang Interchange is located in Xuanwu District in the central city of Nanjing,which is one of the landmark areas of Nanjing's modern and international humanistic green city.Xinzhuang Interchange is also an important part of the centralized transportation system of Nanjing main hub,which is seriously congested during peak hours.On the basis of theoretical analysis,control factors such as road network planning,traffic volume distribution prediction results and current construction conditions,this paper reasonably determines the appropriate Xinzhuang interchange transformation scheme in terms of service level and capacity,project cost and traffic organization during construction period.The design idea and research method are helpful to guide the design of interworking and reconstruction scheme of dense urban areas of the same type.
