摘要
基于火药爆炸理论,超压伤害准则,热通量准则,结合火药库实际情况,采用爆炸数学模型分析法分别对地面火药库爆炸和井下火药库爆炸做出了定量评价,重点研究了爆炸冲击波、热辐射在受限空间与平整地面的伤害效应,并分析了二级乳化炸药的爆热、爆温及TNT当量,通过编制的Mathcad程序进行了计算,得出了各超压、热通量下的伤害距离,同时确定了人员、建筑物及设备的安全距离。
Based on the theory of gunpowder,overpressure damage criterion,heat flux criterion,in combination with the practical situation of powder magazine. Explosion mathematical model analysis,respectively the powder magazine exploded on the ground and underground explosion made a quantitative evaluation,analyses the explosion blast wave,thermal radiation in a limited space,and the damage effect of leveling the ground,level 2 of the emulsion explosive are analyzed and calculated by and TNT equivalent explosion heat,explosion temperature,and through the establishment of a large amount of calculation,Mathcad application under various overpressure,the heat flux are analyzed damage distance,and to determine the safe distance of the personnel,buildings and equipment.
