摘要:
城市轨道交通越行站是快慢车运行模式中需重点研究的技术问题。从国内外常用的越行站站型出发，分析各种站型的优劣，并通过定性及定量分析相结合的方法，对越行站设计时需关注的几个关键问题进行了探讨。分析认为：①高架越行站站型宜优先选择双岛四线站型,地下越行站站型需结合功能需求及工程投资进行选择；②越行线远离站台的站型，快车可不限速越站；③越行线紧邻站台时，若设置站台门，建议过站速度按80 km/h考虑，否则按100 km/h考虑；④为保证运输效率及运营安全，建议越行站选用大号码道岔。
Abstracts:
The overtaking station is a technical issue to be studied in the operation mode of fast and slow trains. According to the commonly used overtaking station layouts in the world, the advantages and disadvantages of various types of overtaking stations are analyzed, some key issues worthy of attention in the design of overtaking station are discussed through the combination of qualitative and quantitative analysis. The research shows that firstly, the double-island-four-line station type is preferred in the elevated overtaking station design, and the types for underground overtaking station can be selected with the combination of functional requirements and project investment; secondly, if the crossing line is far away from the platform, the express train can cross the station without speed limit; thirdly, when the overtaking line is close to the platform, the platform door setting shall consider the passing speed as 80~100 km/h. Lastly, to ensure the transport efficiency and operation safety, the selection of larger turnout is recommended in the design of overtaking station.
