摘要
到发线有效长度是铁路的主要技术标准之一,合理确定到发线有效长度有利于控制车站规模、减少土建工程投资。介绍国内外铁路到发线有效长度的确定原则,借鉴城际铁路和地铁的设计经验,提出按照市域铁路采用的列控系统制式确定到发线有效长度的方法。具体给出:CTCS-2级列控系统下市域铁路贯通式车站和尽端式车站到发线有效长度的算例、图示和说明;CTCS-0级列控系统下市域铁路到发线有效长度算例;ATC系统下到发线有效长度确定的方法以及无配线车站正线股道、有配线车站的侧线股道、岛式站台等多种市域铁路主要到发线形式的有效长度图示和算例说明。市域铁路到发线有效长度与列车长度、安全防护距离和附加余量有关,其中安全防护距离与列车进站允许速度和列控系统关系较大,设计时应重点关注。研究结论可用于指导市域铁路设计,也是对市域铁路设计规范的完善和补充。
As one of the major technical standards of railway, reasonable effective length of receiving-departure track is good for controlling the scale of station and reducing the investment of civil works. In accordance with the design experience of intercity railway and metro, the paper introduces the principle of effective length of railway receiving-departure track home and abroad and puts forward the method of adopting CTCS to identify the effective length as suburban railway. The paper proposes the example, diagram and description of the effective length of suburban railway breakthrough station and end station under CTCS-2; the major examples and diagrams of suburban railway including the example under CTCS-0, the conformation method under ATC and that of non-wiring station main line track, wiring station siding track and island platform. The effective length of suburban railway receiving-departure track is related to the length of train, the distance of safety protection and additional margin, among which the distance of safety protection influences mostly the permitted speed for train entrance as well as CTCS. Therefore, the distance of safety protection should be emphasized while designing the line. The conclusion provides references for designing suburban railway and serves as improvement and supplement for design specifications.
