提速双线的大区间对通过能力的影响

在客货列车速差和站间距增大的情况下,双线自动闭塞区段客货列车运行时分差大于追踪列车间隔时间的大区间将会较多地出现。大区间引起旅客列车扣除系数增加,其增加的幅度与大区间的数量和分布有关。为此提出繁忙干线宜采用旅客列车成组连发的行车组织方法以充分利用通过能力。

The Impact of Long Double-Line Section to Carrying Capacity after Speed-Increasing

With the rising of both station distance and the speed gap betweencargo train and passenger train, there will be more cases of long section where thedifference of running time between cargo train and passenger train is bigger thanthe tracing interval in auto-block sections of double line. Such long section willlead to the increase of deduction coefficient for passenger trains. The range ofthis increase is related to the quantity and distribution of long sections. Thereforethe paper suggests a train operation organization method to dispatch a group ofpassenger trains in a row in order to make fully use of Carrying capacity.
