摘　　要：贵阳至广州高速铁路作为首条运营速度从250 km/h提速至300 km/h的高速铁路线路,分析研究其提速后通过能力的变化,从而指导其他客运专线提速运行具有重要意义。以贵广铁路下行方向提速前后的停站方案为研究对象,将始发终到站相同的列车进行分类,并对同类列车进行停站分组,再将停站分组数与列车停站总次数的比值作为停站系数,进一步判断提速前后区段通过能力的变化情况。结果表明,贵广铁路提速前后某季度运行图停站系数由0.232变化为0.227,结合各车站的停站频率分析,提速后区段通过能力有所提升。该方法简化了停站方案对区段通过能力影响程度的对比研究,对其他提速的高速铁路线路也提供了参考。The Guiyang-Guangzhou High Speed Railway is the first high speed railway line whose operating speed is increased from 250 km/h to 300 km/h,so it is of great significance to analyze the change in its passing capacity after increasing the speed,so as to guide other passengerdedicated lines to increase the speed.By taking the stopping plan of the Guiyang-Guangzhou Railway before and after the speed increase in the downward direction as the research object,the trains with the same departure and destination were classified,and similar trains were included into stopping groups.Then,the ratio of the number of stopping groups to the total number of train stops was used as the stopping coefficient,so as to further judge the change in the passing capacity of the section before and after the speed increase.The results show that the stopping coefficient of the train working diagram of the Guiyang-Guangzhou railway varies from 0.232 to 0.227 in a quarter before and after the speed increase.Based on the stopping frequency at each station,the passing capacity of the section after the speed increase is improved.This method simplifies the comparative study of the impact of the stopping scheme on the passing capacity of the section and provides a reference for other high speed railway lines after speed increase.
