摘要
为研究TNT和温压炸药浅埋爆炸效应的差异性,文章开展了浅埋爆炸试验,系统分析了TNT和温压炸药在爆坑形貌和地表空气冲击波波形等方面的差异.结果表明:相同工况的浅埋爆炸,温压炸药产生的爆坑直径、深度以及体积都大于TNT,装药埋深为0.1m和0.3m时,温压炸药产生的爆坑体积分别是TNT的1.2 倍和2.3 倍.通过对测得的冲击波参数进行比较,分析得出:当埋深为0.1m和0.3m时,比例距离为1 的测点处温压炸药产生的冲击波峰值压力分别是TNT的2.16 倍和1.41 倍;在研究范围内,比例距离和埋深变化对不同类型装药的冲击波冲量衰减量影响很小,但对衰减率有较大影响,当埋深从 0.1m增加为 0.3m时,2 种类型装药的冲量衰减率都增加了近1 倍.
Abstract
In order to study the difference of shallow-buried explosion effects between TNT and thermobaric explosive,shallow-buried explosion experiments were carried out,and the differences between TNT and thermobaric explosive in crater morphology and surface air shock wave waveform were analyzed.The results show that the diameter,depth and volume of the crater produced by the thermobaric explosive are larger than that of TNT under the same working condition.When the depth of charge is 0.1 m and 0.3 m,the crater volume produced by the thermobaric explosive is 1.2 times and 2.3 times that of TNT.By comparing and analyzing the measured shock wave parameters,it is found that when the buried depth is 0.1 m and 0.3 m,the peak pressure of shock wave generated by warm-pressed explosives at the measuring point with a proportional distance of 1 is 2.16 times and 1.41 times that of TNT,respectively;Within the research scope,the change of proportional distance and buried depth has little influence on the shock wave impulse attenuation of different types of charges,but has great influence on the attenuation rate.When the buried depth is increased from 0.1 m to 0.3 m,the impulse attenuation rate of both types of charges is nearly doubled.
