摘　　要：针对双线自闭区段旅客快车扣除系数的计算方法 ,在介绍表格计算法的基础上 ,做了进一步扩展 ,分析了待避站股道足够和不足条件下、货物列车各待避站起停车附加时分不等条件下表格计算法的运用 ;定量分析了旅客列车提速后按闭塞分区追踪运行和按站间闭塞运行扣除系数的变化幅度 ;分析了货物列车提速对改善区段通过能力的作用 ,得出了旅客列车提速后 ,为了不增加提速旅客列车扣除系数 。On the basis of table calculation method and with reference to the calculation method of deduction coefficient of passenger train on double track lines with automatic block, the paper goes a step further and analyzes the table calculation method under the condition of stations with and without sufficient sidings and the condition of freight trains standing at sidings but need different length of time for starting and stopping. The paper also analyses quantitatively the change of deduction coefficient when the train runs in a mode of tracing the block section after the speed increase of passenger trains and when it follows the interval of block. It analyzes the effect of raising freight train speed on the improvement of the carrying capacity. It concludes that after the passenger train speed is raised, it requires the freight trains to raise their speed correspondingly so as not to increase the deduction coefficient of speed increased passenger trains.
