  • 摘要: 为了测定铁路技术站到发车流时空上的不均衡性, 分析了到发车流时间、列车到发数量、技术站衔接方向的特点, 提出了到发车流不均衡性的计算方法。通过分析技术站到发车流的时空不均衡性对技术站的影响, 考虑了不同衔接方向的车流结构、转化范围与到达间隔时间, 设定了线路方向、列车数量等相关参数。应用最大方差比值法, 计算了到发车流时间与不同衔接方向到发车流数量的不均衡程度, 基于基尼系数, 计算了不同时间段车流到发数量的不均衡程度。从空间、时间、数量3个角度将到发车流的三维不均衡特性进行分解, 描述了到发列车数量与时间、空间转换的关系, 建立了铁路技术站到发车流的不均衡三维度量方法, 并以贵阳南站为例进行了实例验证。研究结果表明: 当接车数量为67列、计算时间为12h、接车数水平设置为4时, 不同衔接方向到发车流数量的不均衡程度为0.21, 到发车流时间的不均衡程度为0.03, 不同时间段车流到发车流数量的不均衡程度为0.13。车流总体比较均衡, 符合贵阳南站的实际情况。
