摘　　要：对有3个中间站的城际铁路，将1h内停站列车按单列、2列成组、3列成组3种组织方式，每列车有1，2，3次共3种停站次数，以及有、无待避2种运行方式组成78种停站方案。通过铺画不同停站方案的列车运行示意图，分析计算有、无待避2种运行方式的损失时间，提出有、无待避2种运行方式损失时间的计算公式。按成组列车总停站次数由I到9的顺序，建立无待避停站运行方式损失时间和小时通过能力计算表。计算结果表明：当1h列车停站为4-7次时，小时通过能力为15列左右；不同停站方案对小时通过能力的影响与列车停站次数、停站时间、排列次序以及运行方式等因素有关；因此应根据通过能力利用情况和1h总停站次数的需求选择列车停站方案；应尽可能采用无待避停站运行方式，将有待避停站运行方式作为列车运行调整的备用方案。For intercity railway with 3 intermediate stations, trains may operate respectively with one, two or three trains as a group in an hour, and every train may stop at one, two or three stations. Additionally, taking into account train overtaking, there are 78 stop schemes in total. Based on the train diagrams with various stop schemes, the formulas for calculating the time losses for schemes with and without overtaking are elicited, whereby time losses and the hourly carrying capacity are calculated respectively for train operations with 1 to 9 stops within a train group. Then it can be derived from the calculation results that with 4-7 train stops in total within one hour, the hourly carrying capacity is 15 trains, more or less. The hourly carrying capacity depends on total stops, dwell time, train sequence and operation mode, etc. As a result, stop scheme should be decided in accordance with the carrying capacity utility and hourly total stops. With limited gain in capacity for overtaking schemes, non-overtaking schemes should be adopted as the top priority for shorter journey time.
