摘要:为研究装药比例埋深和比例距离对浅埋爆炸空气冲击波峰值压力的影响,测试了3种比例埋深工况下,7种比例距离处浅埋爆炸空气冲击波的峰值压力,结合量纲分析对试验数据进行拟合,得到了浅埋爆炸空气冲击波峰值压力的经验公式。结果表明:空气冲击波峰值压力随着比例埋深和比例距离的增加而减小;随着比例距离增加,比例埋深对空气冲击波峰值压力的影响减弱;空气冲击波峰值压力ΔPD与装药量Q、爆心距R和埋深L有关,其经验公式为: 。
Abstract:In order to study the influence of proportional burial depth and proportional distance of charges on the peak pressure of shallow buried explosion air shock wave, the peak pressure of shallow buried explosion air shock wave at 7 proportional distances under 3 proportional burial depth conditions was tested. The test data were fitted combined with dimensional analysis, and the empirical formula of the peak pressure of shallow buried explosion air shock wave was obtained. The results show that the peak pressure of air shock wave decreases with the increase of proportional burial depth and proportional distance; With the increase of proportional distance, the influence of proportional burial depth on the peak pressure of air shock wave decreases; Peak pressure of air shock wave ΔPD is related to charge quantity Q, explosion center distance R and burial depth L, its empirical formula is: .
