客运专线到发线有效长研究

研究目的：提出客运专线到发线有效长理论分析及计算、缩短到发线有效长的措施及带来的影响等,对减小到发线有效长度,进而节省站场建设工程投资具有深刻的现实意义。研究方法：本文首先确立了到发线有效长计算原则及应综合考虑的因素,其次对到发线有效长构成理论和列车安全防护距离构成进行详细分析,并选取合适的计算参数计算出到发线有效长,最后对缩短到发线有效长的措施及带来的影响进行分析。研究结论：客运专线到发线有效长与车辆性能、列控模式、车载设备性能和站坪坡度有较大关系。经过理论计算,到发线有效长可在目前国内颁布规定的长度上进一步缩短。

Research on the Effective Length of Receiving-departure Track of Passenger Dedicated Line

Research purposes:This paper establishes the analysis and calculation theory of the effective length of receiving-departure track on Passenger Dedicated Line and presents the measures of shortening its effective length and its impacts thereof,etc.This has profound realistic signification in the saving investment on station and yard construction project.Research methods:First,this paper establishes the calculation principle of the effective length of receiving-departure track and integrated considerations;Second,this paper analyzes in detail the established theory of its effective length and distance for train safe protection.At last analysis has been performed on adopting the proper parameter to calculate its effective length,the measures for shortening its effective length and its effect thereof.Research conclusions:The effective length of receiving-departure track is related to rolling stock's performance,train control mode,train-born equipment's performance,and the grade of station site.It is calculated theoretically that its effective length may be much shorter than the length issued in the domestic regulation.
