6 前言随着我国铁路不断提速的需求,中国列车运行控制系统(CTCS)和调度集中系统(CTC)正在积极发展, 因此影响站场设计的两个重要名词和概念(安全距离和安全线)引起重视。安全距离的长短影响股道有效长,安全线的设置影响站场布置,两者都会引起投资的巨大变化,因而引起重视,甚至争论是必然的。安全距离和安全线是两个概念,但又有内在的联系。 7 安全距离 7.1 影响安全距离长度的因素各种控制模式的列车运行控制系统其安全距离的设置方式是不一样的,鉴于中国列车运行控制系统 (CTCS)的各种等级均采用目标-距离的控制模式, 因此本文仅讨论目标-距离控制模式的安全距离。安
6 Foreword With the continuous speeding demand of China’s railways, the CTCS and CTC are developing actively. Therefore, two important terms and concepts (safety distance and safety line) that affect the design of station yard are caused Pay attention. The length of the safe distance affects the effective length of the stock channel, the setting of the safety line affects the layout of the station yard, and both of them will cause tremendous changes in investment. Therefore, attention is paid to it and even arguments are inevitable. Safety distance and safety line are two concepts, but there are inherent links. 7 Safety Distance 7.1 Factors Affecting the Safety Distance Length The setting of the safety distance for the train operation control system of various control modes is different. Since all levels of China Train Operation Control System (CTCS) adopt the target-distance control Mode, this article only discusses the goal - distance control mode safety distance. Ann
