公路改扩建为城市道路的横断面设计探讨

Discussion on Cross Section Design of Highway Reconstruction and Extension into Urban Road

针对公路改扩建为城市道路需要考虑众多因素的问题,以广州市南沙区番中公路改造为市政路的断面选择为工程实例,对横断面设计的思路进行了探讨。同时,结合项目实际,分别对道路与公路的使用功能差异,以及现状道路、绿化、市政管线等控制要素进行了方案比选论证,为公路改扩建为城市道路的横断面设计提供参考。

Aiming at many factors that need to be considered for highway reconstruction and extension into urban road,taking the cross-section selection of the Fanzhong Road in Nansha District of Guangzhou to be reconstructed into a municipal road as an example,the idea of cross section design is discussed.At the same time,combined with the actual project,the using functional differences between road and highway,and the control factors of current roads,greening and municipal pipelines are compared,selected and demonstrated,which provide the reference for the cross section design of highway reconstruction and extension into urban road.
