摘　　要：随着“一带一路”倡议的推进,丝绸之路经济带沿线国家轨距不同问题对顺利实现互联互通造成的影响愈加显著,套轨技术重要性日益凸显。根据套轨铁路道岔布置复杂、信号设备繁琐等特点,分析研究套轨铁路车站咽喉区以单开道岔将两轨距线路依次分场布置、套轨正线贯通的套轨铁路中间站布置形式;提出以加速度为计算要素、基于不同列车种类和作业类型的车站技术标准占用时间查定方法来计算咽喉区通过能力;根据套轨车站各轨距线路分场布置这一基础条件,提出分别计算不同到发场通过能力,最后汇总得到车站到发线通过能力的计算思路。最终提出调整既有列车运行图降低各类间隔时间、采用标准轨距列车担负部分既有轨距运输任务等方法优化和提高套轨铁路通过能力。With the advancement of the“Belt and Road Initiative”,the impact of different gauge problems in countries along the Silk Road Economic Belt on the smooth realization of connectivity has become more significant,and the importance of rail technology has become increasingly prominent.Based on the characteristics of complex switch layout and cumbersome signal equipment,the differences between the dual-gauge track railway intermediate stations in the throat area of double-gauge railway station were analyzed.According to the different train types and operation models,a method of checking station technical standard occupation time based on acceleration was proposed to calculate the passage capacity at the throat area.Considering the basic condition of the capacity of different arrival and departure fields respectively,this paper summarized the calculation idea of the passing capacity of the station.Finally,the paper proposed to optimize and improve the passing capacity of dual-gauge railways by adjusting the existing train diagram to reduce various intervals and adopting standard gauge train to take on some existing gauge transportation tasks.
