上海市域高速铁路隧道火灾疏散研究

Study on fire evacuation of municipal high-speed railway tunnel in Shanghai

上海市域高速铁路为城际列车和地铁列车共线运行的运营模式,通过数值模拟得到不同通风方式、火源位置、疏散口间距下的人员可用安全疏散时间和必需安全疏散时间,分析人员疏散安全性,为安全疏散设施设置方案提供决策依据。结果表明:地铁列车火灾比城际列车火灾更危险;火灾发生时列车火源位置应尽量停靠在两疏散口之间,且隧道内进行通风排烟;疏散口间距设置为300 m满足城际列车和地铁列车人员安全疏散要求。

The Shanghai high-speed railway is an operation mode of intercity trains and subway trains running on the same line. Through numerical simulation, the available safe evacuation time and necessary safe evacuation time under different ventilation methods, fire source positions, and evacuation gap spacing are obtained, and the evacuation safety of personnel is analyzed, in order to provide decision-making basis for its safe evacuation facility installation plan. The research results show that the evacuation risk of subway train fire is greater than that of intercity train fire;when a fire occurs, the fire source of the train should be parked between the two evacuation openings as much as possible, and the tunnel should be ventilated and exhausted;the evacuation opening spacing is set to 300 m to meet the needs of the requirements for the safe evacuation of personnel on international trains and subway trains.
