针对某厂房发生火灾之后,现场破坏严重,难以开展火灾调查和相关责任追究等现实问题,采用火灾后果数值模拟分析的方法,选择实际的起火部位设定两种不同的火灾场景,并对不同火灾场景下的烟气层安全高度、毒害性、能见度和清晰层温度进行模拟。通过定量和定性的软件分析,判断该厂房是否存在乱堆乱放等违法违规行为,同时通过模拟计算和传统火灾调查结果进行对照,验证模拟计算的合理性,为其他功能厂房或库房的火灾后果计算提供借鉴。
Aiming at the real problems such as serious damage to the site, difficult investigation of the fire and investigation of related responsibilities after a fire in a factory, two different fire scenarios were set by selecting the actual fire site by numerical simulation analysis of fire consequences. Different fires Scene flue gas layer safety height, toxicity, visibility and clear layer temperature simulation. Through the quantitative and qualitative software analysis to determine whether there is disorderly discharge of the plant and other illegal activities, and through the simulation and traditional fire survey results to verify the rationality of simulation, for other functional plant or warehouse fire consequences Calculated to provide reference.
