摘要
应用FDS建立地铁列车车厢模型,设定火灾场景,基于实际情况设定车厢内主要可燃物及其燃烧性能参数,模拟地铁车厢火灾发展情况、温度分布及热释放速率。模拟结果认为,单节列车静止于隧道时,地铁列车火灾峰值温度出现在车厢中部,约972℃,峰值热释放速率约8.8 MW。研究成果可为隧道事故通风与火灾烟气控制研究提供参考。
Using FDS,a model of subway train compartment was built.The fire scene was set.According to the real situation,the main combustibles inside the compartment and their combustion performance parameters were set.The fire development,temperature distribution and heat release rate were simulated.Simulation results showed that,when one compartment was still in tunnel,the highest temperature was at the center of the compartment,being about 972℃,and the peak value of heat release rate was 8.8 MW.The research results can provide reference for the study of tunnel accidental ventilation and fire smoke control.
