| 摘 要： | 建筑火灾会造成人员烧伤、中毒、窒息等伤亡事故。该文对高温、一氧化碳、缺氧等危险因素形成的多因素伤害耦合作用进行风险判断。采用数值模拟的方法构造火灾场景,以此为数据基础,采用二阶聚类的方法,进行多因素伤害风险分析,通过多因素、两因素、单因素风险计算结果的对比,验证了多因素综合风险分析指标选取的合理性,并根据风险计算结果绘...

| Abstract: | Building fires cause casualties in various ways such as asphyxia,poisoning,burning.The coupled injury effects produced by high temperatures,carbon monoxide,and lack of oxygen were analyzed based on a dynamic fire simulator to simulate the fire development.The simulation results were used with a two-step cluster algorithm to analyze multi-factor injury risks due to high temperatures,carbon monoxide and oxygen deprivation.The multi-factor integrated fire risk indexes are shown to be reasonable by comparison w... |
