既有单线铁路直通运行高速动车组提速方案研究

Research on speed increase scheme of high-speed EMU operation for existing single track railway

基于单线铁路吉衡线的曲线要素与既有工程的相关分析,结合邻线赣瑞龙线高速列车运行稳定性试验,对利用既有单线铁路开行高速列车的方案进行研究。得到了吉衡铁路在吉安南—井冈山段具备提速至140 km/h及以上的条件,局部可提速至160 km/h的结论。为利用既有单线铁路开行高速动车组列车,弥补尚不具备新建高速铁路条件地区的地域交流弱势提供参考。

Based on the analysis of the curve elements of Ji’an-Hengyang single track railway and the existing projects,combined with the operation stability test of high-speed trains on the adjacent Ganzhou-Ruijin-Longyan line,this paper studies the scheme of using the existing single track railway to operate high-speed trains,and obtains the conclusion that Ji’an-Hengyang railway has the conditions to increase th e speed to 140 km/h or above in Ji’annan-Jinggangshan section,and can increase the speed to 160 km/h in some parts.The operation of high-speed trains on single track railway can make up for the weakness of regional communication in areas without the conditions of new high-speed railway.
