中心城区主干路改造的设计要点探讨

Discussion on Design Essentials of Main Road Reconstruction in Central City

中心城区主干路一般建成时间较早,随着城市化进程的加快和社会经济的发展,现状市政交通、管线已不能满足沿线用户的需求;路面出现不同程度损坏,影响了行车的安全性和舒适性;沿线各类城市市政设施缺乏统一性和规范性,严重影响了道路交通和城市周边形象,制约了城市形象的提升和进一步发展。针对中心城区主干路改造的设计要点,从道路功能定位、纵断面控制、路面材料、轨道交通协调与管理、现有乔木的处理等方面进行阐述。

The main roads in the central city are generally built earlier.With the acceleration of urbanization and the development of social economy,the current municipal transportation and pipelines can no longer meet the needs of users along the route.The road surface is damaged to varying degrees,which affects the safety and comfort of driving.The lack of uniformity and standardization of municipal facilities in various cities along the line has seriously affected the road traffic and urban surrounding image,and restricted the improvement and further development of the city image.Aiming at the design essentials of the main road reconstruction in the central city,the aspects of road function positioning,longitudinal section control,pavement materials,rail transit coordination,management,and treatment of existing trees are set forth.
