| 摘 要： | 火灾载荷是判断建筑物室内火灾危险程度的依据，以前人们对火灾载荷的研究局限于只考虑可燃物的种类和量，并没有考虑到可燃物的形状、厚度和摆放位置对火灾载荷的影响。该文建立了简单的模型讨论了可燃物的表面积和厚度对火灾载荷的影响，并应用这种模型对三个典型的建筑房间进行了火灾载荷的研究，取得了较好的结果。

| Abstract: | Fire load is a determinative factor in fire risk assessment. Former researchers, in the fire load research, had only taken the type and quantities of the fuel into consideration, ignoring the effect of shape, thickness and position of fuel on fire load. In this paper, several models have been made to discuss the effect of surface and thickness of fuel on fire load, and fire load survey, based on the models, has been made in three different typical occupancies. Last conclusions and suggestions have been given. |
