浅谈城市快速路设计方案的设计——以漳州市东环城路(G324线至南江滨路)为例

Introduction to the Design of the Urban Expressway─Take the East Ring Roads of Zhangzhou(G324 Line to South Waterfront Road) as an Example

随着漳州市中心城区新一轮国省干线路网规划的实施,逐步将原先穿城而过的公路线位调整到城市外围,既有利于城市道路等级和功能的厘清,又优化了整体的路网布局结构。文章较详细地分析了漳州市中心城区东环城路(国道G324线——南江滨路)工程总体设计方案。结合项目建设背景,采用交通量预测的方法,论证了工程建设规模,重点阐述了总体设计方案,主要包括项目的功能定位、主要技术标准、总体线路比选、节点立交方案设计、道路和桥梁标准横断面等。探讨了城市快速路设计方案论证的一般程序。

With the implementation of the provincial trunk road network planning in the center of zhangzhou city, adjusting the highway through the city gradually to the city periphery, both is advantageous to the urban road grade and function to clarify, and optimize the over- all structure of road network layout. This paper introduced the zhangzhou city center east ring roads （ G324 national highway, south water- front road） project overall design in the central urban area. In combination with project construction background, adopting the method of traffic volume forecas, this paper was demonstrated the scale of engineering construction, expounded the overall design, including function orientation, main technical standards, the overall line interchange scheme comparison, node interchange scheme design, road and bridge standard cross section, etc. This paper discusses the general procedure of the design of urban expressway projects.
