客车整备线的数量及能力计算

根据全路各主要客车整备所每列车底占用整备线的时间（ｔ占）和两列车底之间的平均空闲时间（ｔ空），用数理统计方法，按长、短途客车的比例，分别确定ｔ占为８、９、１０ｈ；按每昼夜始发终到客车对数的多少，分别确定ｔ空为３、４、５ｈ；计算出客车整备线的利用系数ａ整和空费系数ａ空。据此可以采用分析计算法，查表法计算客车整备线的数量及能力。可供新建和扩建既有客车整备所参考。

Calculating Quantity and Capacity of Carriage Servicing Tracks

According to the data retrieved from the main carriage servicing depots of the whole railway, the mean occupation time of the servicing track by each train stock tz and the mean idle time between tow train stocks tk are evaluated. In addition with the proportion of the long and short distance passenger trains, tz=8,9,10h, and with the pairs of receiving departare trains, tk=3,4,5h are got respectively by mathematical statistics. Then the utility factor of carriage servicing track azh and the coefficient of idle time tk can be worked out, and the quantity and capacity of the carriage servicing tracks can be estimated by calculation or searching pre-established tables, which is helpful both in constructing a new or extending anexisting carriage servicing depot.
