摘要
随着我国高速铁路网结构日益复杂,动车组实际运用中与线路速度等级不匹配的情况日渐增多。对动车组运用交路中列车与线路速度等级匹配情况进行梳理,分析列车与线路速度等级不匹配的交路,结果显示350 km/h车型下跨250 km/h线路的情况较多,以涉及繁忙高铁干线的跨线交路为主。针对交路中存在的问题提出了优化建议,一是按照局管内高铁线路优化不同速度等级动车组配属,二是加强动车组运用考核,三是提高设备集中度。
With the increasingly complex structure of China's high-speed railway network,there are more and more cases of mismatch between the speed level of the line and that of EMU trains in actual operation.This paper sorts out the speed level matching between the EMU train and the line in the operation EMU routing,and makes a detailed analysis of the EMU routing that mismatches the speed level of the EMU train and the line.The results show that there are more cases of the 350km/h EMU trains crossing the 250km/h lines,mainly involving the EMU routing crossings of busy high-speed rail main lines.In view of the problems in EMU routing,this paper puts forward optimization suggestions:the first is to optimize the allocation of EMU trains with different speed levels according to the high-speed railway lines in the Railways Bureau;the second is to strengthen the assessment of the operation of EMU trains,and the third is to improve the concentration degree of EMU equipment.
