摘　　要：增二线引入既有车站段方案是增建二线的重点、难点,车站段的增二线方案直接影响运输组织的通顺性、方案的可实施性。既有车站设备设施多、车站周围房屋密集,引入条件非常困难。文章结合工程实例,从车站性质、既有车站引入条件、车站站改工程实施难易程度及运输是否顺畅等方面综合考虑,对单线铁路增建二线引入既有车站段线路方案进行研究。文章中列出了5种不同控制因素下增二线引入车站的方式以及对应的车站布置形式,但不管哪种方式的引入最终都要达到增二线引入车站方案运输顺畅、尽量利用既有站设备设施、少站改的要求。Route scheme of existing station is a key and difficult problem for railway additional second-line. The additional second-line scheme of the existing station directly influences the smoothness of transportation organization and the implementation of the scheme. Since there are lots of equipment and facilities in the existing station andlots of houses around the station, it is very difficult to introduce additional second-line in station section. Based on the engineering examples, research is conducted on route scheme from the nature of station, the lead-in conditions of additional second- line in existing station section, the degree of difficulty of station reconstruction project, whether the transportation is smooth and other aspects. In this article, different ways of introducing additional second line into station under 5 different control factors are listed as well as their corresponding station layouts, but regardless of which way will be taken, they have to meet the requirements of smooth transportation, making full use of the existing station equipment and facilities, less station renovation.
