在双线区间设有分歧线路或双线插入段条件下,怎样合理铺划列车运行线并据此计算区间通过能力是铁路现场长期存在和争论较多的课题。本文作者在实际工作中总结出一种所谓“参考线”方法,并通过按实际需要对参考线平移调整等步骤,可选择出上下行运行线最佳配合方案,把车站间隔时间影响压到最小,从而最大限度地发挥设备效能,获得较大通过能力。对缓和有关能力限制区段特别是枢纽通过能力紧张状况提供了一种较简捷的铺图方法,并通过实例对通过能力提出了比较符合实际的分析方法。
How to rationally train the train line and calculate the passing capacity of the interval is a long-standing and controversial issue on the railway site under the condition that there are different lines or double-line insert sections in the double-line section. In the actual work, the author summarizes a so-called “reference line” method, and through the actual needs of the reference line translation and other steps, can choose the best combination of the upper and lower line of operation to minimize the impact of the station interval , So as to maximize equipment efficiency, access to greater capacity. It provides a relatively simple mapping method for mitigating the capacity constraints, especially for hubs, through capacity tensions and provides a more realistic analysis of capacity through examples.
