客运专线“X”形接轨站布置方案探讨

Discussion on the Layout Schemes of X-shape Junction Station of Passenger Dedicated Line

研究目的:"X"形接轨站布置图型的选择决定着相关客专的点线能力是否协调,区间能力能否有效发挥,在设计工作中应予以高度重视。本文对"X"形接轨站影响区间能力的因素进行分析,通过对几种接轨站布置图型方案的优缺点进行分析和探讨,提出各布置图型的适用条件。研究结论:(1)线路别布置方案对车流及跨线车流具有极大的适应性,应优先采用两端布置联络线方案中的两线均到达端设跨线车联络线方案,其次可采用一端布置跨线车联络线方案;(2)方向别布置方案较适合于两条客专标准有差异且不办理或少量办理客运作业的接轨站布置;设跨线车联络线立体疏解的完全方向别布置方案适合于两条客专车流和跨线车流均较大的情况,应优先采用进站端设跨线车联络线的方向别车站布置方案;采用平面交叉的部分方向别布置方案仅适用于其中一条客专车流较小且各线跨线车流不大的情况;(3)本研究成果可为客运专线接轨站设计提供参考。

Research purposes： Layout pattern choice of X- shape junction station will determine whether the station and line capacity of relevant passenger dedicated line is coordinated and interval ability can play an effective role, in the design work we should attach great importance to. The reasons which impacting section capacities on X - shape junction station are analyzed in this paper. Layout schemes of X - shape junction station are proposed after detailed discussions on the advantages and disadvantages of several schemes, meanwhile the suitable condition is advised for each scheme. Research conclusions：（ 1 ）Layout schemes oriented track have wide adaptability to train flow and crossing train flow. The scheme, which connecting lines are located at each arrival throat section among the schemes connecting lines are located at both of station, is adopted in priority, and the schemes which connecting lines are located only one side of station are adopted in the second place. （2） Layout schemes oriented direction usually apply to the case where the criterions of passenger dedicated lines are different and no or small passengers transportation service in the junction station. The schemes oriented absolute direction with vertical separation connecting line for crossing - track trains are reasonable when the train flow and crossing train flow is both great, layout scheme oriented direction which the connecting line for crossing - track trains are located at each arrival throat section is preferred solution. The schemes oriented partial direction with plane crossing only apply the case where the train on the line and the crossing train flow is small. （ 3 ） The research resuhs can provide some references for the design of junction station of passenger dedicated line.
