摘　　要：为了研究LPG储罐泄漏危害范围的变化规律,以一典型LPG压力储罐为例,针对LPG泄漏事故后果类型,结合危害范围的模拟方法,借助ALOHA软件,对LPG储罐泄漏事故及泄漏可能导致的火灾爆炸事故的危害范围进行了模拟,确定了LPG储罐泄漏扩散危害范围,从而确定应急救援时的安全间距。研究结果为现场指挥员制定决策提供量化依据,为现场应急救援队提供决策依据,同时也可为应急预案的制定提供科学依据。In order to study the hazardous range and degree of the impact for LPG storage tank leakage,a LPG storage tank was taken as an example,according to the types of LPG leakage accident,combined with the simulation method of hazardous range,with the help of ALOHA software,the hazardous range of LPG storage tank leakage accident and fire and explosion accident caused by leakage was simulated,and the hazardous range of LPG storage tank leakage diffusion was determined,so the safety distance of emergency rescue was determined.The research results can be used to assess the risk in emergency plans.
