摘　　要：防止列车在车站内发生侧面冲突,是信号联锁系统设计的安全要求之一。国际铁路项目中通常采用“侧冲防护”功能对列车之间可能发生的侧面冲突进行防护。介绍了目前海外铁路项目中普遍采用的传统侧冲防护方案;分析了传统侧冲防护方案的优势及其局限性;在传统侧冲防护方案的基础上,结合工程实际应用,提出一种在不降低联锁逻辑安全性的前提下,最大限度提升运输作业效率的侧冲防护解决方案。To prevent the train from flank collision in the station is one of the safety requirements in the design of interlocking system.In international railway projects,the function of"Flank Protection"is usually used to protect the possible side collision between trains.This paper introduces the traditional solutions to flank protection widely used in overseas railway projects.The advantages and limitations of the traditional flank protection solutions are analyzed.Furthermore,based on the traditional flank protection scheme,a new-type flank protection solution that can maximize the efficiency of transportation operations without reducing the safety of the interlocking logic is provided in combination with practical engineering applications.
