山地城市干线道路关键技术分析——以贵阳市为例

Analyses on Critical Aspects of Arterial Roads in Mountainous City of Guiyang

为完善山地城市规划和综合交通系统,需对山地城市干线道路规划设计进行深入研究。通过对山地城市旧城区和新区发展模式的介绍,分析了干线道路在山地城市中的作用。从地形地貌、城市空间布局、交通出行及道路网等方面分析了山地城市特性。在此基础上,针对山地城市干线道路规划设计在功能定位、技术标准、交通组织等方面的特殊性,结合贵阳市城市干线道路建设案例,对山地城市干线道路的功能与标准、交通廊道、线形设计、横断面、新技术理念等提出了技术建议。

In order to perfect the planning and integrated traffic system of mountainous city,it is required to further study the planning and design of arterial roads of mountainous city.By analyzing the old urban area and new area development modes of mountainous city,the function of the arterial roads in the mountainous city is analyzed.The characters of mountainous city are analyzed from the aspects of topography,urban spatial layout,transportation and road network.On this basis,aiming at the particularities of the arterial road planning and design of mountainous city in the aspects of functional orientation,technical standard and traffic organization,combined with the construction case of arterial roads in Guiyang,the technical suggestions of functional standards,traffic corridor,geometric design,cross section and new technical idea of arterial roads in mountainous city are put forward.Finally,the development orientation mountainous city road construction is pointed out.
