城市地下快速路进出口布置与交通功能关系研究

Relationship Between Location Planning of Underground Expressway Access and Traffic Function

通过阐述城市地下快速路系统的定位及其交通功能,以及城市地下快速路进出口布置与其交通功能的关系,分析出地下快速路起终点进出口、中间进出口及地下空间联系进出口布置与地下快速路系统交通功能的关系及对地面路网的影响。结合地下工程的特点初步探讨城市地下快速路进出口布置原则。

The function and effect of underground expressway network are expounded in this paper as well as the relationship between the access location of underground expressway and traffic function.The relationship between the access both at endpoint and intermediate of the expressway and traffic function of underground exp-ressway network is discussed.The influence of access location at endpoint and intermediate of the expressway is also discussed in this paper.The principle of access location of underground expressway is preliminarily introd-uced according to the characteristics of underground engineering.
