既有线上提高列车运行速度对运输能力的影响

Effect on Traffic Capacity by Raising train Running Speed on Existing Lines

针对既有线旅客列车提速的要求,从分析影响线路通过能力的主要因素着手,分析了旅客列车最高速度提到140、160和200km/h后对线路通过能力的影响,提出了在不降低当前已有的运输能力条件下,客货列车速度匹配关系以及在兼顾提速与扩能时应注意解决的问题。

Aiming at requirement of speed-raise for passenger trains on the existing lines the paper analyses the effect of max speed up to 140, 160 and 200 km/h for passenger trains on the line carrying capacity starting with the main factors effecting the line carrying capacity. The paper puts forward the matching relation between the passenger and freight train speeds and problems to be solved taking account of speed-raise and enlarging capacity without a decrease of present carrying capacity.
