武汉新城区轨道交通系统制式研究--以武汉轨道交通19号线为例

Research on the Mode of Rail Transit System in Wuhan’s New Urban Area--A Case Study of Wuhan Rail Transit Line 19

随着武汉主城区联网,中心区域地铁线路已逐步建成,将进一步加大城市外围及敷设周边组团市域线路建设力度。根据线路特征,考虑经济性、快速性需求,需选择一种适宜的系统制式。本文以武汉轨道交通19号线为例,结合其于城市外围线路长、中运量特点,对市域快轨、胶轮系统和中低速磁浮系统制式进行适应性分析,从速度、舒适性、环保、技术可靠性、系统维保、四网兼容、产业支撑、综合规模等角度进行综合比较后,推荐采用市域快轨系统方案即可实现预期目标。

With the connection of the main urban area of Wuhan,the subway line network in the central area is gradually formed,the construction of urban peripheral and surrounding suburban lines will be further strengthened.According to the characteristics of the line,considering the economic and speed requirements,it is necessary to choose a suitable system mode.Taking Wuhan Rail Transit Line 19 as an example,this paper analyzed the adaptability of urban rapid rail,rubber wheel system and medium and low-speed maglev system for suburban lines characterized by urban periphery,line length and medium capacity,and made a comprehensive comparison from speed,comfort,environmental protection,technical reliability,system maintenance,compatibility of four different transportation networks,industrial support,comprehensive scale and other aspects.As a result,an urban rapid rail system is recommended to be adopted,which can achieve the desired goals.
