摘要
应用爆炸理论分析一起餐饮店燃气泄漏引发的爆炸事故。在事故现场勘查的基础上,根据事故现场破坏状况,判定事故爆炸点;依照蒸气云爆炸模型和冲击波超压准则,定量给出爆炸威力;采用TNT当量法确定了气体泄漏量,同时分析了事故原因,为燃气爆炸事故调查分析提供参考。
Gas explosion accident caused by leakage in a restau- rant was analyzed in explosion theory. The center of the explo- sion was determined by investigating the destroy situation of the scene of the accident on the basis of site survey of the accident. The power of the explosion was calculated quantitatively ac- cording to the vapor cloud explosion model and the shock wave overpressure criterion. The gas leakage amount was obtained by TNT equivalent method and the cause of the accident was ana- lyzed. The results provide reference for the investigation of gas explosion accidents.
