摘　　要：在大尺寸铁路隧道模型内,结合实际环境、列车高度和车窗高度对铁路隧道内细水雾灭火系统的喷头进行布置,开展实体试验,研究灭火系统的有效性。结果表明,结合车窗布置的喷头喷射出的细水雾能够快速覆盖在列车内部火源周围,在短时间内扑灭列车内部火灾,而隧道上方喷头喷射的细水雾能够有效的衰减热辐射,抑制火势进一步发展。因此,在隧道内结合列车高度和车窗高度设计出的喷头布置方式,能够对列车火灾进行较好的控制。In the large-scale railway tunnel model,combing with the reality,the height of the train and the window,the nozzles of the water mist fire extinguishing system inside the tunnel were ar.ranged,and full scale experiment was carried out to study the effi.ciency of the fire extinguishing system.Results showed that,water mist from the nozzle arranged according to the window can cover the fire inside the train fast,and put out the fire in a short time,while water mist from the nozzle on the top of the tunnel can effec.tively reduce the heat radiation and suppress the fire development.So arranging nozzle combining with the train height and window height can suppress the fire effectively.
