【摘要】 研究目的:市域快速轨道交通快慢车运行模式下，越行站的设置直接影响工程投资、运营效率及运营安全，是快慢车运行组织规划设计中的重点问题之一。开行快慢车的数量和比例对越行站的设置有重要影响，本文以重庆市轨道交通27号线快慢车运行组织设计为例，运用越行站分布计算方法，计算分析快慢车开行比例对线路通过能力、越行站设置数量、越行站设置位置的影响规律，并给出越行站设置的相关建议。研究结论:(1)较小的开行比例更能够兼顾通过能力和快慢车开行数量，较大的开行比例可以提升线路通过能力但会损失快车数量；(2)当通过能力一定时，快慢车开行比例的改变几乎不影响越行站的数量；(3)在靠近端点车站设置越行站，线路可以更好地适应不同快慢车开行比例；(4)本研究成果可为市域快轨越行站的设置和快慢车行车组织方案的制定提供参考和借鉴。更多还原

【Abstract】 Research purposes: Under the mode of express/local trains of urban express rail transit, the setting of overtaking stations affects the project investment, operation efficiency, and operation safety, which is one of the key problems in the planning and design of express/local train operation organizations. The number and operation proportion of express/local trains have an important impact on the setting of overtaking stations. This paper takes the operation organization design of express/local trains of Chongqing rail transit line 27 as an example, calculates and analyzes the influence of express/local train proportion on the line capacity, the number of overtaking stations, and the location of overtaking stations based on the overtaking station distribution calculation method. Suggestions are given for overtaking stations settings.Research conclusions:(1) A smaller train proportion can better take into account the line capacity and the number of express/local trains. And a large train proportion can improve the line capacity, but the number of express trains will be lost.(2) The change of train proportion has little impact on the number of overtaking stations when the line capacity is certain.(3) By setting overtaking stations near the terminal stations, the line can better adapt to different operation ratios of express/local trains.(4) The research results can provide reference for the setting of overtaking stations and the design of the organization scheme of express/local trains in urban express rail transit.更多还原
