摘要研究目的:地铁快慢车模式中，越行点的设置与行车密度、快慢车始发间隔、工程实施条件等因素相关，同时应具备不同行车密度下的兼容性。合理确定越行点是快慢车模式研究的关键部分，本文结合以上影响因素，从理论上对越行点的确定方法进行总结，为工程前期研究提供理论依据。研究结论:(1)从越行点的设置原则出发，分析越行点设置所受影响因素，其中快慢车始发间隔、列车开行密度对越行点的确定影响最大；(2)基于分析结论，提出在快慢车比例为1 ∶1且快车均匀发车的情况下，越行点的分布是有规律的，并总结出越行点的设置原则公式；(3)提出快慢车比例非1 ∶1的情况下，越行点的设置原则；(4)通过运行图铺画，对以上理论研究进行验证，结果表明理论研究与运行图铺画结果是一致的；(5)研究成果可以为工程前期研究和行车组织设计提供理论依据，为今后快慢车模式的相关标准、设计规范制定提供参考。

Abstract：In the metro express/slow train mode, the setting of overtaking point is related to mutiple factors such as train densities, launching intervals of the express/slow train and the engineering implementation conditions, in addition, the system compatibility under different train densities is strongly required. The key to the express/slow train mode research is how to reasonably determine the train overtaking sites. Combined above influencing factors, conclusion was made on the strategy of over-taking sites determination, and theoretical basis was provided for preliminary engineering research.Research conclusions:(1) Starting from the setting principles of the train overtaking sites, this paper analyzed the influencing factors of it. The train operation density and the launching interval of express/slow train have the greatest influence on the determination of the train overtaking sites among all the influencing factors. (2) Based on the analysis conclusions above, this paper came up with the point that the distribution of the train overtaking sites was regular in case the ratio of express and slow train was 1 ∶1 and the departure of the express train was uniform, then summarized the setting principle formula of the train overtaking sites. (3) The setting principle formula of the train overtaking sites was proposed in case the ratio of express and slow train wasn't 1 ∶1. (4) The theoretical research above was verified through drawing working diagram, the result of theoretical research was proved to be the same as drawing working diagram. (5) The research achievement will provide theoretical basis to preliminary engineering research and train orgnization design, and will provide a reference to make future standards and specifications of express/slow train mode.

Key words： urban rail transit express/slow train mode overtaking point train working diagram
