摘　　要：以锥形量热仪的试验数据为基础,利用表面火蔓延模型和层次分析方法分别推导构建能够描述固体建筑材料和具有熔融流动行为的热塑性建筑材料火灾危险性的综合评价指标。将4种不同厚度的胶合板、PVC板和3种热塑性材料的火灾危险性综合评价指标与大尺寸火灾试验进行对比,结果表明,该火灾危险性综合评价指标能够较好地反映建筑材料的实际火灾危险性。Based on the data from cone calorimeters,the fire risk assessment index of solid building materials were gotten by surface fire spreading model,and the fire risk assessment index of thermoplastic building materials with melt flow properties were gotten by AHP.The index of plywood of 4 different thickness,PVC and 3 kinds of thermoplastic materials werecompared with large scale fire experiment,and the results showed that the index can reflect the fire risk of building materials well.
