摘要
北京轨道交通新机场线是一条服务于北京新机场的专线,线路全长41 km,平均站间距19 km,初步客流预测远期高峰小时断面约5 800人/h,旅行时间目标为从市内航空主客源地至新机场北航站楼半小时到达。从线路长度、站间距及机场专线的旅行时间目标来看,本线宜采用最高运行速度140 km/h及以上车辆。结合本线线路敷设方式、资源共享条件及车辆技术成熟度等,本线车型及最高运行速度选择受到一定限制。当前国内市域快轨发展面临技术标准不明确、线网层次不清晰等问题,新机场线作为特殊的市域快轨,其车辆选型受线路功能定位、乘客乘坐舒适度、旅行时间等多种因素影响,需结合多方面因素综合考虑。从新机场线的特殊性及设计目标入手,对本线最高运行速度、车辆型式的选择进行分析,得到本线适宜采用最高运行速度160 km/h、在城际动车组成熟平台基础上进行改进的市域型车的结论。
New Airport Express （NAE） in Beijing is an express line between Beijing New Airport and the city center, totaling almost 41 km with an average station spacing of 19kin. The evaluated maximum passenger volume is 5,800 prs/h and the target travel time is less than 30minutes. The running speed of 140km/h or higher may be selected according to the line length and the station spacing. However, the maximum speed of rolling stock is limited because of tunnel section, resource sharing conditions and vehicle manufacturer. Regional rail development lacks technical standards and its construction is slow in China. As a special regional express rail, the vehicle selection of NAE has significant influence on passenger comfort, travel time and system function. A 160km/h maximum speed and an optimized regional vehicle based on CRH6F are recommended according to NAE＇s design targets.
