摘　　要：研究目的:铁路技术规范规定遇到进站信号机外制动距离内进站方向超过6‰下坡道时应设接车进路的延续进路,以防列车冒进出站信号机后发生侧面冲撞事故。但是设置延续进路会带来车站列车通过能力的下降或增加工程投资等问题。客运专线铁路是否还需要采用该规定,对此进行分析与探讨,提出不宜设置的可能性,供工程设计者参考。研究结论:通过分析既有线6‰下坡道延续进路设置的由来,结合客运专线铁路车辆制动性能及列车运行控制装备水平的提高,提出了客运专线车站站外有超过6‰下坡道时无需设置延续进路的论点,突破了铁路技术规范的规定,对降低铁路轨道和信号工程投资、减少铁路用地、提高车站列车通过能力有现实意义。Research purposes： The Chinese Railway Specifications says the successive route of receiving has to be set when there is a 6‰descending grade in the range of braking distance out of the home signal to prevent side collision accident in case that train overruns the start signal. But setting successive route decreases the station carrying capacity and increases the investment. This paper discusses the issue on whether or not to set the successive route for 6‰ descending grade on passenger dedicated line and gives the possibility of not setting the successive route for 6‰ descending grade on passenger dedicated line for providing the reference. Research conclusions：Through analyzing the reasons for setting the successive route for 6‰ descending grade and the sophistication of the braking capability and control equipment of the train running on passenger dedicated line, the idea is expressed in this paper that it is unnecessary to set the successive route when there is a 6‰ descending grade on passenger dedicated line. This idea breaks through the regulation significance to decreasing the investments in the railway track and si of The Chinese Railway Specifications, but has gnaling equipments, reducing the land occupation and enhancing the traffic capacity.
