地铁车辆段调车作业冲撞车挡事件分析

Analysis method for bumper collision incident in subway depot shunting operation

近年来,不同原因、不同类型的地铁运营安全事件时有发生,确定事件发生原因、制定整改措施和预防措施是避免事件重复发生的有效途径。以地铁车辆段调车作业冲撞车挡事件为例,介绍该类事件的过程分析方法,推算出列车冲撞车挡的速度,精确还原调车过程中列车运行的状态,准确指出事件发生的原因,从而确定解决措施的关键点。

In recent years, different causes and different types of subway operation safety incidents occur frequently. Identifying and determining the causes of the incidents, formulating counter measures and preventive control is an effective way to avoid the repeat of similar incidents. Taking the bumper collision incidents in a metro depot shunting operation as an example, this paper introduces the process analysis method of this category events, calculates the speed of train collision, accurately portray the state of train operation in shunting scenario, accurately identifies the causes of the incident, and determines the key points of measures taken.
