【摘要】 对BLEVE的三种主要灾害模式,火球辐射、超压以及碎片抛射进行了研究,研究总结了各自的灾害计算模型及相关的伤害准则,采用STATISTICA6.0对火球直径、持续时间进行了重新拟合,给出了爆炸能量计算模型中不确定性参数的选取方法,对碎片抛射的各个不确定性参数的分布进行了总结。根据总结得出的模型,采用VB6.0编制了BLEVE事故后果分析软件,并分别以球罐、丙烷的热BLEVE算例及卧罐、二氧化碳的冷BLEVE算例对软件的计算功能进行演示。更多还原

【Abstract】 BLEVE’s three main vulnerability vectors,radiation(fireball),overpressure(blast)and impact(fragment),were studied in this article,and the hazard estimating model and harm rule were concluded respectively.STATISTICA6.0 was used to regress new equations for fireball radius and fireball duration.Confirmation methods were proposed for uncertain parameters of the explosion energy estimating model.Distribution functions for all uncertain parameters of fragment projectile were also collected.Based on these models,VB 6.0 was used to develop the BLEVE consequence analysis system,and two cases(1.sphere tank/propane/hot BLEVE,2.cylindrical vessel/carbon dioxide/cold BLEVE)were selected to demonstrate the function of the system.更多还原
