Abstract:
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.
