基于圈层结构的高铁枢纽交通集疏运体系研究

Research on transportation collection and distribution systems of high-speed railway hubs based on the circle structure

大型高铁枢纽影响范围广、影响差异大、枢纽本身功能复杂,以枢纽为核心不同半径范围的交通集疏运体系在功能、设施布局、规模上也存在较大差异。从高铁枢纽圈层理论切入,提出了圈层结构交通特征与主要问题,基于圈层结构提出了高铁枢纽交通集疏运体系外围、中间和核心三个圈层的交通集疏运发展策略。最后以高铁长沙西站为例,构建了适合该站的综合交通集疏运系统,能有效指导下阶段控规编制与工程方案设计。

Large high-speed railway hubs have a wide range of influence,great differences,and complex functions.Transportation collection and distribution systems with different radius within hubs also have great differences in function,facility layout and scale.On the basis of circle theory of high-speed railway hubs,this study investigated the traffic characteristics and main problems of the circle structure.Further,the development strategies were proposed about the peripheral,middle and core circles of transportation collection and distribution system of highspeed railway hubs.Finally,taking Changsha west railway station as an example,a comprehensive transportation collection and distribution system was developed,which can effectivelyguide the planning and engineering scheme design of the next stage.
