建筑火灾轰燃的影响因素与预测

为了预防建筑火灾轰燃的发生,提出了在建筑的设计阶段,应从建筑内可燃物的燃烧特性、通风情况、壁面内衬材料、建筑面积和形状等因素着手,采用综合预测方法对设计方案进行评估和验证,并提出了各因素变化对发生轰燃影响程度的无量纲重要度参数,通过比较各因素参数绝对值的大小,找出轰燃的重要影响因素,从而为制定有效的整改方案提供依据。

On Influential Factors and Prediction of Flashover in Buildings

In order to prevent the flashover in buildings when they are in the stage of being designed,this paper proposes that the flammability of combustible materials,the ventilation situation,the liner materials of walls and the area of the room should be concerned.Then a synthetic flashover predicting method can be used to assess and check the designing plan.A non-dimension parameter is created to show the influence degree of each factor to flashover.On the basis of comparing the absolute values of parameters,the...
