摘要 利用火灾科学国家重点实验室的模型实验楼,对多层多室建筑室内火灾时,烟气运动过程的规律进行研究,实验过程主要对烟流成份、温度、气压差和烟流速度等进行测量与分析,并基于国家标准“工作场所有害因素职业接触限值(GBZ2-2002)”对烟流成份对人的危害情况进行分析.结果表明:多层多室建筑火灾时,着火源点垂直高度上温差最大,随着烟流蔓延和扩散,烟气层温度基本趋于一致.对于木垛火灾和煤油火灾,最先超过一般人的生理极限的主要成份是SO2,CO和CO2,其次是NO和NO2.多层建筑火灾过程中,由于烟流的气压差波动幅度及频率较大,容易导致烟流在流动过程中充分蔓延到所流经通道的每一个空间,使人员避灾难度加大.
