摘要
采用ALOHA软件对引起LPG罐车爆炸的事件进行研究,对四种主要的火灾爆炸的后果闪火、蒸汽云爆炸、池火灾和BLEVE爆炸事故进行模拟计算,定量得出每种事故危害的影响范围。分析爆炸事故最容易导致的后果,在特定的幕景下,结合爆炸区域的人群密度,计算出事故影响范围的伤亡人数。结果表明LPG储罐爆炸可能造成严重的事故后果,所以运输过程中应积极采取安全预防措施,同时应建立起完善的事故后应急措施,以减少事故发生后的人员伤亡。
ALOHA software was used to research on the incident which was caused by explosion of LPG tanker. Four consequences of flash fire, steam cloud explosions, tank fire and BLEVE explosion were calculated in the simulation, the influenced scale of each scenario was quantified. The consequence which was easily resulted in after explosion accident was analyzed. Combined with the crowd density of the influenced field, the number of people who＇re dead and injured was calculated. The result indicated explosion of LPG tank car was likely to cause serious consequences. Safety precautions and emergency measures after the accident during transportation should be taken to avoid an accident as far as possible, and to cut down casualties after an accident.
