城市主干路拓宽改造设计的新思路

New Idea of Urban Main Road Widening and Reconstruction Design

城市道路具有一定的通过性、服务性的"公共"属性。其中,通过性涉及公路、道路规范中所提出的通行能力要求、车道数量要求和宽度要求等,借助断面经济性的设置来维护通行效率,为社会经济的进步提供帮助。服务性则是在满足宽度、景观带需求的同时,依附于通过性。当前在城市精细化管理的发展进程中,对城市道路的实用功能、品质等提出了更高的要求,尤其是主干路,如何进行拓宽改造设计成为首要解决的问题。针对此,论文研究城市主干道路的问题,提出几点拓宽改造设计的新思路,旨在为增强城市主干路的服务性与通过性夯实基础。

Urban roadshave certain public properties of passabilityand service. Among them, the traffic capacityrequirements, the number of lanes and the width requirements put forward in the highway and road specification are involved, and the traffic efficiency is maintained by the setting of section economy, so as to provide help for the progress of social economy. While meeting the needs of width and landscape belt, service is attached to passability. At present, in the development process of urban fine management, higher requirements have been put forward for the practical function and quality of urban roads, especially for trunk roads, so how to broaden and transform the design has become the primary problem to be solved. In view of this, this paper studies the problem of urban trunk road, and puts forward several new ideas of widening and reforming design, aiming at strengthening the service and passability of urban trunk road to lay solid foundation.
