高铁网络化背景下普铁与城市的冲突与协调

Conflict and Coordination Between Regular Railway and Cities in the Network Era of High-Speed Railway

随着高铁网络逐渐完善,在高铁、普铁共存的复合型通道上,普铁的功能逐渐发生分化,包括客货兼顾、以货为主、全部货运等。普铁与城市空间格局和城市功能随之出现了一系列的冲突,或是使原有冲突更加严重。首先分析高铁开通和逐渐成网对普铁的影响,提出普铁运输面临的三个问题:普铁与城市空间的冲突、普铁对货运系统的支撑和普铁专用线的优化利用。针对三个问题,通过案例形式总结普铁线路和城市功能的特征及匹配性,并分类别提出解决思路。

As the network of high-speed railway develops progressively,the functionalities of regular railway start to change along railway corridors served by both high-speed and regular railways.Those changes occur in passenger and freight mixed transportation,freight-dominated transportation,and freight-only transportation.A series of conflicts between the regular railway and urban spatial layout,regular railway and functionality of city have appeared,or the original conflicts have become more serious.This paper first discusses the impacts of the initial and networking operation of high-speed railways on the regular railways,and points out the three problems facing the regular railway transportation:the conflict between regular railways and urban space,the support of regular railways to freight system,and the optimization of special regular railway lines.By summarizing the characteristics of regular railway lines and urban functionality and the level of their compatibility through case studies,the paper proposes the problems solutions accordingly.
