研究目的:在复杂艰险山区,站坪长度往往受限,桥隧相连。本文通过对立即折返(立折)列车在车站的作业流程分析,研究不同的车站平面布置型式中通过列车、立折列车作业交叉对车站作业能力的影响,得出不同的立折列车对数所适应的站型布置,研究出合理的站坪长度,为复杂艰险山区铁路选线及有立折列车作业的客运站设计提供借鉴。研究结论:我国的客运专线、高等级铁路正处于快速发展阶段,线路所连接均为经济据点,主要有直辖市、省会城市及地市级城市。省内交流和长途客流(省际及跨省客流)往大型经济据点集中,从而形成较大经济据点车站有立折列车和通过列车,并产生一定的作业交叉干扰。根据经济据点的规模大小,立折列车对数有较大的差别,存在交叉干扰严重程度差别较大。本文研究的不同站型布置及折返作业方式均有相适应的立折列车对数规模及合理的站坪长度,对复杂艰险山区铁路选线及车站的设计将有一定的指导和借鉴作用。
Research purposes: In complex and difficult mountainous areas, the length of the station is often limited and the bridge and tunnel are connected. Through the analysis of the operation flow of immediate reentry (vertical folding) train at the station, this paper studies the influence of train cross-over operation on the operational ability of the station in different type of station layout, and draws a conclusion that different pairs of folding train logarithm Adaptable station layout, study a reasonable length of station, in order to complex and difficult mountainous area railway route selection and the operation of the passenger station design provide reference. Research conclusions: China’s passenger dedicated line and high-grade railway are in a rapid development stage. All the lines are connected with economic bases, including municipalities directly under the Central Government, provincial capitals and prefecture-level cities. Inter-provincial exchanges and long-distance passenger flows (inter-provincial and inter-provincial passenger flows) are concentrated in large-scale economic bases to form larger economic positions. There are fifties and semitrailers passing through trains and generating cross-interference from certain operations. According to the size of the economic base, there is a big difference between the logarithmic train number, and there is a big difference in the severity of cross-interference. In this paper, different types of station layout and reentry operations are adapted to the logarithmic scale of flipping train and reasonable length of station, which will guide and reference railway alignment and station design in complicated and dangerous mountainous areas.
