多线引入的高铁车站到发线能力核算方法

Calculation Method of Arrival and Departure Capacity of High-speed Railway Station Introduced by Multiple Lines

铁路车站的到发线能力是点线能力协调工作中重要制约环节。随着我国高速铁路网络日益完善,多线引入的高铁车站增多,车站到发线承担多重功能的情况也随之增多。为合理确定到发线能力,以苏州园区站为例,采用不同的核算方法对车站的能力控制股道进行分析。研究结果表明,采用单一的理论计算法或者铺画运行图法所得出的固定数值结论一般具有片面性,而将2种方法结合所得出的结果可以更好地反应车站到发线的能力范围。这种方法既能充分利用车站到发线能力,又能游刃有余地进行运输组织的调整,为将来多线引入的高铁车站到发线能力核算提供一种新的思路和方法。

The arrival and departure capacity of a railway station is an important constraint in the coordination of point and line capacity.As China’s high-speed railway network is becoming more and more perfect,the number of high-speed railway stations introduced by multiple lines has increased,and the situation in which the arrival and departure lines of stations undertake multiple functions has also increased.In order to reasonably determine the arrival and departure capacity,this paper takes Suzhou Industrial Park Station as an example,and uses different accounting methods to analyze the capacity.The research results show that the fixed numerical conclusions obtained by using a single theoretical calculation method or a running diagram method are generally one-sided,but the results obtained by combining the two methods can better reflect the capacity range.This method can not only make full use of the station's arrival and departure capacity,but also adjust the transportation organization with ease.This paper will provide a new idea for the calculation method of the arrival and departure capacity of high-speed railway stations.
