摘　　要：针对城轨交通领域列车驶离站台时,因突发紧急情况,乘客拉下车厢内紧急制动阀运营场景,对信号系统施加紧急制动的有效范围进行讨论。通过紧急制动停车后车体留存在站台有效区域的长度,推导出信号施加紧急制动的有效范围;对比至少有一扇车门在站台有效区域、至少有一扇车门在站台门有效区域和至少有一节车厢在站台门有效区域等3种方案的优缺点,以此作为运营管理重要的参考依据。Aiming at the operation scene of that passengers pull down the emergency brake valve in the carriage due to sudden emergency situations when the train leaves the platform in the field of urban rail transit,the effective range of emergency braking applied by the signal system is discussed.The effective range of emergency braking applied by the signal is derived from the length of the effective area reserved by the train body at the platform after emergency braking.And the advantages and disadvantages of three schemes that at least one door in the effective area of the platform,at least one door in the effective area of the platform door,and at least one carriage in the effective area of the platform door are compared,which can be used as an important reference for operation management.
