大跨度大空间建筑火灾内攻战术研究

Study on Internal Attack Tactics of Fire in Large Span and Large Space Buildings

大跨度大空间建筑人员物资密集、火灾荷载大,发生火灾后燃烧猛烈,火势蔓延迅速,极易形成大面积立体火灾,且该类建筑主体构件受热后容易变形坍塌,极易造成人员伤亡,扑救难度较大。该文通过梳理比对近年来大跨度大空间建筑火灾,从内攻难点、内攻时机、内攻行动环节、内攻突破口、内攻路线、内攻推进方式这6个方面对内攻战术进行了详细分析,为大跨度大空间建筑火灾的有效控制和迅速扑救提供一定参考。

Buildings with large span and large space have dense personnel and materials, large fire load, fierce burning after fire and rapid spread of fire, which is easy to form a large three-dimensional fire. Moreover, the main components of such buildings are easy to deform and collapse after heating, which is very easy to cause casualties and difficult to put out the fire. By combing and comparing the fire of large span and large space buildings in recent years, this paper analyzes the internal attack tactics in detail from six aspects: internal attack difficulties, internal attack timing, internal attack action links, internal attack breakthrough, internal attack route and internal attack promotion mode, so as to provide some reference for the effective control and rapid fire fighting of large span and large space buildings.
