单线半自动闭塞区段提速旅客列车扣除系数

Deduction Coefficient of Passenger Train on Speed-up Single-Track Lines

旅客列车提速,会改变客货列车速差,引起旅客列车扣除系数和非平行运行图通过能力的变化.通过理论研究和模拟分析,确定了单线半自动闭塞区段提速旅客列车扣除系数的变化规律和取值范围.提速旅客列车对数较少时,扣除系数波动幅度较大,反之较小.扣除系数有随旅客列车速度提高而减小的趋势.当提速旅客列车在10对以上时,扣除系数为0.8～1.1,且在0.9～1.0之间的几率较大,建议取0.85～1.15.

Raising the speed of passenger trains will change the speed difference between passenger and freight trains, resulting in changes in the removal coefficient of the passenger trains and the passing capacity on a nonparalleled train diagram. The variation range of removal coefficients of raisingspeed passenger trains in semiautomatic block zones on a single railway line is determined through theoretical study and simulation. The variation range is large when the number of passenger trains is small, and vice versa, and tends to decrease with the increase in the speeds of passenger trains. When the number of passenger trains is over 10 pairs, the removal coefficient is in the range of 0.8 to 1.1, being most likely between 0.9 to 1.0. It is suggested to take the removal coefficient in the range of 0.85 to 1.15.
