摘　　要：液化天然气槽车发生火灾爆炸时,极易引起周围人员伤亡和建筑损坏,运用火灾爆炸量化分析方法建立了液化天然气槽车火灾爆炸模型,定量分析了20t液化天然气槽车爆炸后果,结果表明BLEVE爆炸中火球热辐射是主要的危害;10s内人员死亡半径、二度烧伤半径和一度烧伤半径分别为43m、124和196m;93m^109m处的建筑物玻璃被震碎。最后针对评价结果提出了该类事故的灭火救援对策。Casualties and building damage are caused by LNG tanker fire and explosion. Quantitative analysis was applied to establishing fire and explosion models of LNG tanker wagons. And the explosion aftermath of a 20t LNG tanker wagon is analyzed by quantitative method. The results showed that the fireball radiation is the major hazard of BLEVE. In 10 seconds, death radius, the radius of second-degree and first-degree burns are 43m, 124m and 196m. The building glass is shattered from 93m to 109m. Finally, countermeasures of fire fighting and rescue are proposed based on evaluation results.
