摘要
为研究爆炸冲击波对人的损伤与防护问题,分析了爆炸防护人员损伤的阈值问题,并以"Jose Henrych"经验式为计算模型,探讨了标准TNT炸药在不同当量条件下、在空气自由场中点爆炸时冲击波的变化规律。在此基础上得出了不同装药量时的鼓膜损伤和不同死亡率下的安全距离,经验证,所得结果是准确、可行的。
In order to study the problem of human body injury due to blast wave and obtain protection method, the injury threshold values of blast protecting persons are analyzed. Taking the famous ＂Jose Henrych＂ experience formula as calculating model, the change rule of point source blast wave in the air free field is discussed under the condition that standard TNT explosives is in different equivalent. On this basis, safe distances of drum injury and different mortality rate are obtained. The results obtained are proved to he exact and feasible.
