摘　　要：到发线安全防护距离涉及行车安全、行车效率及工程投资。在不同信号系统下,到发线安全防护距离的计算方法不尽相同。阐述安全防护距离的定义、组成,分析在不同信号系统下安全防护距离受约束的相关因素;以两种典型的信号系统为例,详细讨论不同方式下到发线安全防护距离的计算方法,为实际的到发线有效长研究提供借鉴。The safety protection distance of arrival and departure track affects train operation safety,efficiency and project investment.In different signal systems,the calculation method of the safety protection distance is different.In this paper,the definition and composition of the distance are presented,the relevant restrictive factors affecting the length of the safety protection distance under different signal systems are analyzed.The calculation method is further discussed based on two typical signal systems,in order to provide reference for calculating the length of actual arrival and departure track.
