摘要:

在城市轨道交通大小交路开行方案下,中间折返站能力为线路运输能力的关键因素.本文分别针对中间站站前折返与站后折返,根据列车折返作业流程,分析列车在中间站的最小间隔时间,建立列车间隔时间的计算模型;并考虑列车接发车作业与折返调车作业之间的冲突,分析有作业干扰情形下的车站能力.案例表明:小交路列车开行比例越高,车站的发车能力越小,但不发生作业干扰时,大小交路开行方案对车站能力的影响较小;而在有产生作业干扰情形时,站后折返能力损失可能达30%以上,要高于站前折返.在实际运营过程中,有必要合理安排通过列车在中间折返站的到站时间,以减少作业干扰、避免线路能力损失.

Abstract:

In multi- routing mode of urban rail transit, the capacity of intermediate turn-back stations is a key factor to determine the carrying capacity of the rail line. According to the process of train turn-back, this paper proposes a computation model to calculate the minimum time intervals between trains at intermediate stations with station-front and station-behind turn-back, respectively. With the consideration of route conflict between short-routing train and long-routing trains, its impact on station capacity is analyzed. Case studies show that the station capacity decreases slightly with the increase of the ratio of short- routing train. Route conflict may lead to the loss of the station capacity by more than 30% at station-behind turn-back station, which is higher than that at station- front station. It is important to design reasonable arrival times of longrouting trains at intermediate turn-back stations in order to avoid the route conflict and the capacity loss.
