摘要： 研究地铁隧道人员安全疏散可靠度，为安全疏散设施设置提供决策依据。采用FDS 建立某隧道列车火灾模型，研究不同排烟模式下列车中部火灾人员可用安全疏散时间。采用Pathfinder 软件模拟不同疏散场景下的人员疏散过程，获得人员必需安全疏散时间。采用SPSS 软件进行正态分布分析，计算不同疏散场景下的人员安全疏散可靠度。结果表明：采用纵向通风排烟可有效提高人员安全疏散可靠度，在火源位于疏散口中间和疏散口处时，可分别提高82.48%和86.62%；相同疏散条件下，人员疏散可靠度随火源功率以及疏散口间距的增大而减小，而疏散门宽度对人员疏散可靠度几乎无影响。

Abstract: The study of reliability of personnel safety evacuation insubway tunnel can provide decision-making basis for its safe evacuation facilities setting. FDS was used to establish the tunnel train fire model, study the available safe evacuation time of personnel in fire at the middle of train under different smoke exhaust modes.Pathfinder was used to simulate the evacuation process of people in different evacuation scenarios and the required safe evacuation time was obtained. SPSS was used to analyze the normal distribution and calculate the safety evacuation reliability of personnel in different evacuation scenarios. The research results showed that the vertical ventilation and smoke exhaust can effectively improve the safety of personnel evacuation. When the fire source is located at the middle of the evacuation port and at the evacuation port, it can be increased by 82.48% and 86.62% respectively. Under the same evacuation conditions, the evacuation reliability decreases with the increase of the fire source power and the distance between evacuation exits, while the evacuation door width has little effect on the evacuation reliability.

Key words: subway tunnel, train fire, personnel evacuation, evacuation reliability
