摘要
以火灾成长概率和火灾发生后的过火面积为评价指标,探讨舰艇火灾危险性等级评估方法。运用火灾动力学与统计理论耦合的火灾风险评估方法,对舰船火灾危险性进行评估。依据火灾动力学和火灾发展过程中不同阶段的特点,将火灾由初期发展蔓延到整个防火分区的过程划分为4个阶段。使用概率Petri网对舰船火灾发生过程进行了建模,并在此基础上,建立了火灾发生过程概率计算的算法。根据不同阶段火灾的特点,求得了各阶段火灾的临界时间,并以此为基础对火灾发生后舰船舱室平均过火面积计算进行了研究。计算结果表明,该方法通过对火灾过火面积的计算判断出火灾的蔓延情况和对火灾控制较弱的设计环节。
Based on the method of fire dynamics and probability statistics,the method of ship fire risk evaluation was presented.The probability Petri net was used to model the process of the ship fire.According to fire dynamics and different characteristics in fire growth,the process was divided into four phases.Based on the probability Petri net,the calculation method of the probability of every fire process was built.According to the characteristics of every stage of ship fire,every fire critical time was calculate...
