非典型城市立交节点设计案例研究

A case study on the design of non-standard urban interchange

随着我国城市化建设的快速发展,部分现有的道路交通设施已无法满足城镇化需要,其中一些重要的立交节点矛盾尤为突出,存在功能不完善、交通组织混乱等问题。同时,受到周边已建成道路、建筑等因素的制约,不能以“单点集散”的常规思路应对,如何因地制宜地处理好各类交通需求,与城市路网良好衔接是很多地区需要解决的问题。文章以南京应天大街长江隧道生态科技岛节点改造为例,综合现状痛点、周边限制条件、区域路网规划等因素,保障各类交通流有序组织,经过方案分析比选,最终确定立交总体设计方案。

With the rapid development of urban construction in China,some traffic facilities are no longer able to meet the needs of urbanization,some important interchange are particularly contradictory,with problems such as incomplete functions and chaotic traffic organization.At the same time,due to the constraints of existing roads,buildings,and other factors in the surrounding area,the conventional approach of“single point distribution”cannot be used to cope with it.How to handle various transportation needs appropriately and connect well with the urban road network is a problem that many regions need to solve.This article takes the renovation of the Eco Hi-Tech Island interchange of the Yangtze River Tunnel of Yingtian Street,Nanjing as an example.Taking into account factors such as current pain points,surrounding constraints,and regional road network planning,it ensures the orderly organization of various traffic flows.After scheme analysis and comparison,the overall design plan of the interchange is finally determined.
