摘　　要：快慢车模式在国内城市轨道交通中实践应用已较为普遍,但关于快车在越行站的2种越行模式研究还存在一定不足。基于国内外研究现状与运营案例分析,通过优化并建立既定停站和越行站方案下的系统能力计算公式,并结合运行图铺画验证,系统论证了2种越行模式在系统能力、运行效率及越行站设置等方面的具体差异和适应条件。研究结果表明,从功能和成本角度考虑,越行站宜设置为双岛四线、高架站方案;快车不停站越行模式是慢车待避时间更短、系统能力损失更少、越行站设置数量更少的方案,适合在设计阶段采用;同时考虑到设计与实际客流特征可能存在差异,也提出在运营阶段调整为快车停站再越行模式的影响及相应措施。相关成果可为快慢车模式的设计和运营提供有效参考。The application of fast and slow train modes in urban rail transit in China is becoming increasingly common,but there is still a lack of systematic research on the two overtaking modes of fast trains at overtaking stations.By analyzing the current research status and practical cases in China and abroad,the system capacity calculation formula was optimized and established under the existing stopping and overtaking schemes and verified by the train working diagram.The specific differences and adaptation conditions between the two overtaking modes were systematically demonstrated in terms of system capacity,operational efficiency,and overtaking station setting.The research results indicate that from the perspective of functionality and cost,the overtaking station should be set up with a double-island and four-line structure or elevated station.The nonstop overtaking mode is a solution with shorter waiting time for slow trains,less system capacity loss,and fewer overtaking stations,which is suitable for the design phase.At the same time,the possible differences between the design and actual passenger flow characteristics are considered,and the impact and corresponding measures of adjusting to first-stop and overtaking mode for fast trains during the operation phase are proposed,which can provide an effective reference for the design and operation of fast and slow train modes.
