【摘要】 随着我国客运专线网络的逐步成型,旅客在出行方式的选择上有了较大改善。安全、方便、快捷逐渐成为旅客出行方式选择的重要考虑因素,这对铁路运输产品提出了更高的要求,客运专线上旅客列车的公交化运行将成为一种趋势。在客运专线上,列车采取公交化运行时必须要整个线路的点线能力协调配合才能保证列车持续、高效的运转。作为客运专线上的点——客运站,其通过能力将成为整个线路通过能力的瓶颈,如何对客运站设备尤其是咽喉区平面布局才能保证列车在站更有效的运转?本文立足于此,从客运专线客运站车场以及咽喉区的布置着手分析,对于客运专线客运站咽喉区在公交化运行条件下应满足的条件以及如何优化进行了研究,主要内容包括以下几个方面：1.对铁路客运站咽喉区的基本结构和组成进行了简单的概述,并对目前客运专线咽喉通过能力的影响因素、计算特点和计算方法进行了总结,分析了不同性质的客运专线车站的列车作业性质和作业过程。2.对客运专线咽喉区布置形式的影响因素进行了探讨,分析了各个因素对于站场咽喉区结构元素影响机理,并对咽喉区基本结构单元的参数进行了分析和处理,作为咽喉区平面设计的参考原则。3.基于二叉树的理论,将咽喉线束区梯线中道岔、圆曲线、夹直线等抽象为二叉树中的结点,结合站场设计中的相关限制条件,提出了基于计算机的最优叉树梯线布置方案的方法,为计算机实现车站梯线方案的自动设计提供可行的基础。对咽喉进路区的道岔与渡线的配置进行了分析,探讨了其配列形式如何满足车站作业进路要求。4.基于公交化运行条件,对相邻列车的作业间隔对车站咽喉区长度的限制进行了解析计算,得出了不同间隔时间条件下咽喉区长度的限制值。在此基础上,建立了咽喉区布置优化模型,并根据咽喉设计的实际,将模型进行分解求解,结合实例,得出了可行的解。论文将客运专线车站咽喉区分为咽喉进路区和咽喉线束区两个部分进行分析,总结了咽喉区结构布置的自动化设计的限制条件和步骤,为利用计算机实现咽喉区网络结构的自动生产奠定了基础,能够对客运专线车站咽喉区平面布置进行定量、定性的分析,并对咽喉区平面布置进行优化。更多还原

【Abstract】 With the step-by-step forming of China’s passenger dedicated network, the choice of passenger’s travel mode has been greatly improved. Security, convenient, fast have been important consideration for traveling choice, which demand the rail transport products higher, and then public transport operation of passenger dedicated line will become a trend. On the passenger dedicated line, the train runs as the public transport operation, the ability of the point and the line of the entire line should coordinate with the train in order to ensure sustainable, efficient operation. As a point of the line,the passenger station’s ability will become bottlenecks of the whole line’s ability. How to layout the equipments of the station, especially the throat area in order to make the train runs more efficiently in the station? This article is based here, proceeding with an analysis of the arrangement of the yard and throat area of the station, studying the throat area of the station should satisfy which condition and how to optimize under the terms of the public transport operation. The main contents include the following aspects:1. This paper expounds the basic structure and composition of the throat area of railway passenger station, and summarizes the characteristics and methods of the count of the capability of the throat area of the station, and analyzes the operating properties and the operating process of the different nature of the PDL2. The paper investigates the influencing factors of the arrangement of the throat area of the station of PDL, and analyzes various factors how to affect the structural elements of the throat area of the yard, and analyzes and deals with the parameters of the basic structural unit of the throat area, which is used as the reference to the principle of graphic design of the throat area.3. Based on the theory of binary tree, the paper abstracts the turnout, clipping, circular curve, straight line as nodes in the binary tree, which are in the ladder line of the wiring harness of the throat area. Combining with the related constraints in the design of the yard, the optimal binary tree is proposed based on computer ladder line layout method, for the computer to realize automatic station stairs line scheme is designed to provide feasible basis. Throat route to the rail and cross the line configuration are analyzed, and discussed its column form how to meet the requirement of the route of the station.4. Based on the public transport operation, the paper made the analytic calculation on the limitation of the adjacent train operation interval on the length of the throat area of the station, draw the limit of the length of the throat area under the condition of different time interval. On this basis, the throat area layout optimization model is established, and according to the actual design of the throat, the model decomposition method, combining with the instance, the feasible solution is obtained.In this paper, the throat area of the station is divided into route area and throat harness area two parts for analysis. The paper summed up constraints and steps of the automatic design of the layout of the throat area structure, which lay the foundation for the automatic generation of network structure of the throat area by computer. This can be used for quantitative and qualitative analysis of the layout of the throat area of the PDL, and the optimization of the layout of throat area.更多还原
