200-250km·h^-1客货共线铁路列车速度匹配研究

Study on the Train Speed Matching of 200-250 km · h^-1 Mixed Passenger and Freight Railway

以250km·h^-1和200km·h^-1旅客列车作为基本列车，计算停站基本列车、普通旅客列车（160km·h^-1）和货物列车（120和80km·h^-1）的扣除系数。采用扣除系数法，计算不同速度列车共线运行时的通过能力。计算结果表明，以通过能力不低于110对作为标准，在200km·h^-1速度等级的铁路上，200km·h^-1旅客列车可以与80km·h^-1或120km·h^-1货物列车共线运行，在250km·h^-1速度等级的铁路上，250km·hv旅客列车可以与120km·h^-1货物列车共线运行，但不宜与80km·h^-1货物列车共线运行。

250 km·h^-1 and 200 km·h^-1 passenger trains were taken as the basic trains to calculate the deduction coefficients of stop basic trains, ordinary passenger trains （160 krn ·h^-1） and freight trains （120 km·h^-1 and 80 km ·h^-1）. The carrying capacities of different speed trains running on the same line were calculated by using deduction coefficient method. Results show that, with the carrying capacity no less than 110 pairs as the standard, on 200 km ·h^-1 speed level railway, 200 km·h^-1 passenger trains can run on the same line with 80 km ·h^-1 or 120 km·h^-1 freight trains. On 250 km·h^-1 speed level railway, 250 km ·h^-1 passenger trains can run on the same line with 120 km ·h^-1 freight trains, hut cannot run on the same line with 80 km ·h^-1 freight trains.
