昆明市域东西快线系统选型研究

System Selection of Kunming East-West Metropolitan Express Line

近年来,我国各大城市对市域快线建设需求巨大,其中系统选型是快线规划建设中的焦点之一。以昆明东西快线为研究对象,总结国内城市市域快线选型经验,分析建设规划阶段客流预测及工程方案对系统选型的要求,提出以速度、运能、舒适度、景观、工程可实施性为评价指标,综合比选城市轨道车辆A型车、B型车及国铁CRH6型动车组,初步提出适宜东西快线的系统制式,以期为今后大城市和都市圈市域铁路的系统制式选择提供参考和依据。

In recent years,the construction of regional express lines has attracted the attention of large cities in China.System selection is one of the most important tasks for express line construction.Using Kunming’s East-West express line as an example,this paper summarizes the method of system selection for regional express lines in China,and presents the system selection requirements from the perspective of passenger flow forecasting and engineering schemes.An evaluation system that includes the speed,capacity,comfort,landscape,and feasibility is proposed.Using a comprehensive comparison of type A and B vehicles,and CRH6 EMUs,an East-West express line system is determined.This study provides a reference for the system selection of express lines in China’s large cities and metropolitan areas.
