山地城市道路路网结构布局及设计优化——以重庆市江津鼎山“江洲湾”片区路网为例

Layout and Optimization of Road Network Structure in Mountainous Cities--Taking Dingshan"Jiangzhouwan"District in Jiangjin,Chongqing as an Example

为解决山地城市道路路网规划难度大、设计不合理的问题,分别从城市总体规划和路网专项层面,以城市景观、土地利用、功能布局、路网规划、路网结构、建设投资等为切入点,并以重庆市江津鼎山“江洲湾”片区路网为例,结合规划设计要点,对鼎山“江洲湾”片区的规划路网进行研究与优化。实例表明,本文提出的规划设计要点可为道路规划设计提供指导。

In order to solve the problems of difficult road network planning and unreasonable design in mountain cities,this paper analyzes on urban landscape,land use,functional layout,road network planning,road network structure,construction investment,etc.,from the aspects of urban master planning and road network special planning,and takes the road network of the Jiangzhouwan area of Dingshan in Jiangjin of Chongqing as an example.Combined with the key points of planning and design,the planned road network of Dingshan"Jiangzhouwan"area is studied and optimized.The example shows that the key points of planning and design proposed in this paper can provide guidance for road planning and design.
