中国城市道路隧道分布及发展特征

Distribution and Development Characteristics of Urban Road Tunnels in China

通过对406座城市道路隧道的信息搜集整理,从通车年份、分布省市、穿越类型(水体、建筑、山体)、洞体类型(长度、速度、车道)、洞口类型(多洞口、朝向、分离、下沉、曲线)等方面对中国城市道路隧道进行统计分析,清晰直观地反映中国城市道路隧道的发展规模,展示中国城市道路隧道的建设特点,对中国城市道路隧道进一步发展研究提供基础支持。

Based on the information collection and sorting of 406 urban road tunnels, the statistical analysis of urban road tunnels in China is carried out from the aspects such as the year of service, provinces and cities where road tunnels are distributed, the obstacles passed through(water, buildings, mountains), tunnel types(length, speed, lane)and portal types(multiple portals, orientation, separation, subsidence, curve), which clearly and directly reflects the development scale of urban road tunnels in China, shows the construction characteristics of urban road tunnels in China, and provides basic support for further development research of urban road tunnels in China.
