西永组团Ah片区路网设计研究

Study on Design of Road Network in Ah Area of Xiyong Group

随着城市规模不断扩大,中心城区的外围城区及组团不断增加。由于外围城区及组团所处的区位、功能定位及发展阶段不同,其路网设计需要综合考虑各方面因素。以西永组团Ah片区路网设计为例,对Ah片区对外交通联系、与周边组团的衔接进行了梳理,对轨道线位进行了论证,并充分考虑路网结构优化、路网竖向设计及土石方平衡、路网建设时序等因素,使路网设计能满足片区路网交通需求及城市规划管理的需要。

With the enlarging urban scale,the outlying districts and groups of the central city continue to grow.As the district locations,functional orientations and development stages of the outlying districts and groups are different,the road network design needs to consider all factors comprehensively.Taking the design of road network in Ah Area of Xiyong Group as an example,the external traffic links of Ah Area and the connection with the surrounding groups are sorted out,and the rail alignment is demonstrated.The factors of optimizing the road network structure,vertical design of road network,balancing the earth and stone,and construction sequence of road network are fully considered which make the design of road network able to meet the traffic demand of road network in the area and the demand of urban planning management.
