京沪高速铁路在越行情况下的通过能力研究

Study on the Capacity of Beijing-Shanghai High Speed Railway under Overtaking Condition

京沪高速铁路标杆车的存在,使得京沪高速铁路存在越行情况,越行造成的通过能力的浪费也是困扰京沪高速铁路运营的重要因素之一。分析国内外现有的铁路通过能力的研究成果,结合京沪高速铁路实际运营现状,以不停站列车为标准,确定每列车因越行需要从高速铁路平行运行图上扣除的不停站列车的列数(扣除系数),分析了不同越行方案下越行列车的扣除系数,并且根据分析结果对京沪高速铁路运行图铺画提出了相关的建议。

The benchmark trains on Beijing - Shanghai high speed railway have to overtaking other trains. Overtaking is one of the important factors that disturb the operation of Beijing - Shanghai high speed railway. Based on the analysis of existing railway line capacity, this essay takes non-stop trains as compare unit, determines the number of trains that should be cancelled in parallel train timetable due to over taken (deducing coefficient). Meanwhile, the author analyzes the capacity of Beijing - Shanghai high speed railway under different overtaking conditions, proposes advice on the train diagram drawing with the aim of maximizing the line capacity utilization.
