摘要:
目的：为使越行站的建设更贴合“以人为本”的设计理念，并尽量保障运营的灵活性，需合理选择越行站站型。为此，需对各种越行站站型在工程投资及运营方面的优劣进行研究探讨。方法：归纳总结了常用的越行站站型，运用定性及定量分析相结合的方式，从工程投资、运行效率及运营特点等方面，深入研究各站型的优劣及适用性。结果及结论：在慢车开行数量大于快车开行数量的快慢车混合运行线路中，双侧四线方案及单岛四线方案在工程投资及提升快车运行效率方面虽具备一定优势，但对慢车运行效率的影响更大，且不利于灵活运营，故在站型选择时，除考虑降低工程投资、提升快车运行效率外，还应尽量减少对慢车乘客的影响，并考虑为灵活运营创造条件。建议高架越行站优先选用双岛四线站型；地下越行站若兼顾停车线功能，为保障运营的灵活性，采用双岛四线亦是有利的。

Objective: To align the construction of overtaking stations with the ′peoplecentered′ design concept and ensure the operation flexibility, it is necessary to select appropriate overtaking station types. Therefore, it is essential to research and explore the merits and shortcomings of various overtaking stations in terms of engineering investment and operation. Method: Commonly adopted overtaking station types are summarized, and a combined qualitative and quantitative analysis approach is employed to thoroughly investigate their strengths, weaknesses, and applicability in terms of engineering investment, operational efficiency, and operation characteristics. Result & Conclusion: On mixedoperation lines where the number of local trains exceeds that of express trains, the doubleside fourtrack scheme and the singleisland fourtrack scheme have certain advantages in terms of engineering investment and express train operational efficiency improvement. However, the above schemes have a greater impact on local train operational efficiency and are not conducive to flexible operation organization. Therefore, in the station type selection, it is important to consider not only reducing engineering investment and improving fast train operational efficiency， but also minimizing the impact on local train passengers and creating conditions for flexible operation. It is recommended to adopt doubleisland fourtrack station type preferentially for elevated overtaking stations. For underground overtaking stations with parking line function, the use of doubleisland fourtrack scheme is also favorable to ensure the operation flexibility.
