【Abstract】 Gas explosion accident caused by leakage in a restaurant was analyzed in explosion theory.The center of the explosion 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 according 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 analyzed.The results provide reference for the investigation of gas explosion accidents.更多还原
