超高层建筑火灾扑救难点和灭火救援战术重点运用分析

Analysis on the Difficulties of Fire Fighting in Super High-Rise Buildings and the Key Application of Fire Fighting and Rescue Tactics

针对超高层建筑灭火救援问题,提出外攻与内攻相结合的救援战术,解决高层建筑火灾蔓延速度快、复杂结构不利于救援的难题。研究结果表明,通过灭火救援战术的应用,可结合建筑平面结构确定疏散口,从CO体积分数、烟气层高度、烟气层上下温度、与火源的距离等方面综合分析,准确找出最佳进攻点位与路径,并科学实施救援与撤离工作,使火情得到有效控制,救援目标高效完成。

Aiming at the problem of fire fighting and rescue in super high-rise buildings,this paper puts forward the rescue tactics of combining external attack with internal attack to solve the problem that the fire in high-rise buildings spreads quickly and the complex structure is not conducive to rescue.The research results show that through the application of fire fighting and rescue tactics,the evacuation exit can be determined in combination with the plane structure of the building,and the best attack point and path can be accurately found from the aspects of COvolume fraction,smoke layer height,smoke layer temperature,distance from the fire source,etc.,and the rescue and evacuation work can be scientifically implemented,so that the fire can be effectively controlled and the rescue target can be effectively completed.
