摘要
针对国内某烟花爆竹厂爆炸毁伤事故,在现场调查的基础上,对该爆炸事故的爆炸冲击波毁伤效应提出了若干分析计算模型。通过综合运用空气冲击波超压估算药量和抛掷距离核算药量的方法得到事故厂房单个工作间的存放药量约为4.3 kg,超过了单个工作间允许的最大存放药量4.0 kg。从而对事故酿成的毁伤结果给出了科学合理的解释。药量的估算方法可为类似事故的调查提供借鉴。
Based on field investigation of an explosion accident in a fireworks factory, an analysis model of the explosion shock-wave damage effect was put forward. Through the integrated use of the overpressure of explosion shock-wave and the throwing distance, the explosive charge was estimated. The result shows that the explosives stor- age charge was 4.3 kg ,which exceeded the maximum charge in a single room with 4.0 kg. Then ,a reasonable expla- nation on disaster evaluation was given for this accident, which could be considered as a reference for other similar accidents.
