摘　　要：随着我国高速铁路成网运营,点、线能力不匹配的问题日益凸显,尤其是多条线路汇集的咽喉区成为限制车站通过能力的主要瓶颈。同时,列车密集到发,车流高度集中,高峰时段列车进出站频繁,进路交叉干扰加剧,这些特征均对车站咽喉带来很大压力。因此,结合国内外学者已有研究,从咽喉通过能力计算着手,阐述咽喉通过能力动、静态影响因素,以进路为研究对象、车站拓扑图为依托,结合牵引计算,提出了基于道岔分组的咽喉通过能力图解思想及步骤。最后,以西安北郑西场为实例,将既有列车到发顺序作为输入流,经图解模型,得到最优进路分配方案视作输出流,并对结果进行定量分析。分析表明:相比于利用率法,图解法计算结果更准确,同时又能反映接发车进路所占用道岔组及时长。With the network operation of high speed railway in China,the problem of mismatch between point and line capacity has become increasingly prominent.Especially,the throat area where multiple lines converge has become the main bottleneck limiting the carrying capacity of stations.At the same time,the dense arrival and departure of trains,the highly concentrated traffic flow,the frequent entry and exit of trains during peak hours,and the intensified interference of route intersections all bring great pressure to the throat of the station.Therefore,combined with available research,starting from the calculation of throat capacity,this paper expounded the dynamic and static influencing factors of throat capacity.Taking the route as the research object,the paper considered the station topology,adopted traction calculation,and put forward the graphic idea and steps of throat capacity based on turnout grouping.Finally,regarding the Zhengzhou-Xi’an yard of Xi’anbei Station as an example,the paper took the arrival-departure sequence of existing trains as the input flow.Through the graphical model,the optimal route allocation scheme was obtained as the output flow,and the results were analyzed quantitatively.The analysis shows that compared with the utilization method,the calculation result of the graphical method is more accurate,and it can reflect the turnout group and duration occupied by the arrival and departure routes.
