摘　　要：采用扣除系数法对快慢车模式下的城市轨道交通线路通过能力展开研究。先根据扣除系数理论设定基准列车,并以某线路若干个中间站为例设定列车越行的判定条件;然后确定模糊开行比例范围、铺画5种不同开行比例及越行次数的列车运行图,并分别列出扣除系数、损失通过能力及实际通过能力的计算表达式。最后以上海轨道交通16号线为例,结合线路输送能力及客流需求进行对比分析,确定高峰时段线路通过能力最佳的开行比例。The deduction coefficient method is used to study the carrying capacity of urban rail transit lines under the express and slow train mode.Firstly,the benchmark train is set according to the deduction coefficient theory,and the judgment conditions of train overtaking are set as examples by taking some intermediate stations on a certain line;secondly,the range of fuzzy operation ratio is determined,five different operation ratios and the number of overtaking trains are used to draw the train diagram,the calculation expressions of deduction coefficient,loss capacity and actual passing capacity are listed separately.Lastly,with Shanghai metro Line 16 as an example,and according to a comparative analysis of transport capacity and passenger flow demands of the line,the optimum proportion of transit line carrying capacity in rush hours is determined.
