摘　　要：选取当前在城市交通隧道中较为常见的三种灭火系统(泡沫-水喷雾联用系统、水喷雾灭火系统、细水雾灭火系统),以相关地方标准和工程案例为参考确定设计参数,开展全尺寸灭火试验分析研究不同灭火系统在隧道中的实际灭火效能。试验结果表明,泡沫-水喷雾联用系统的灭火时间最短;水喷雾灭火系统可以有效控制火势,降低环境温度;细水雾灭火系统能够灭火,但灭火时间较长。Choosing three common fire extinguishing systems which are common in existing urban traffic tunnel(foam-water spray fire protection system,water spray fire protection system and water mist fire extinguishing system),and referring to relevant local stan-dards and engineering cases,full scale fire extinguishing experi-ment was carried out to analyze the efficiency of their fire extin-guishment in tunnel.The results showed that fire extinguishing time of foam-water spray fire protection system is the shortest;wa-ter spray fire protection system can effectively control fire and re-duce ambient temperature;water mist fire extinguishing system can put out fire successfully with relatively longer fire extinguish-ing time.
