摘要:
为了研究乳化炸药空中爆炸冲击波的衰减规律,利用空中爆炸测试系统测定了乳化炸药空中爆炸的冲击波超压。根据试验数据,提出了描述冲击波超压峰值与比例距离关系的修正经验式,并将试验数据和经验公式计算值进行了对比分析。结果表明:当比例距离z=L/W1/3≤2.4时,修正公式与除Mills公式以外的其他经验公式吻合得较好;当z=L/W1/3>2.4时,修正公式与所有经验公式基本吻合。通过对比,乳化炸药空中爆炸修正经验式可应用于工程爆破实践,对于减少空气冲击波危害具有重要的理论和实际应用价值。
Abstract:
In order to study the attenuation rule of shock wave in air explosions of emulsion explosive, overpressure of shock wave in air blasting of emulsion explosive was measured by the an air blast test system. Based on the experimental data, a modified empirical formula to describe the relationship between peak value of overpressure of shock wave and proportional distance was proposed. Meanwhile, experimental data and calculated values of the new empirical formula were compared and analyzed. Results show that the new empirical formula agrees well with the other empirical formulas except for Mills formula when the proportional distance z=L/W1/3≤2.4,and when the proportional distance is greater than 2.4, the new empirical formula is in good agreement with all empirical formulas. Through comparative analysis, the improved empirical formula of air explosions of emulsion explosive, which has theoretical and practical significance for reducing the damage of air shock wave, could be applied to the practice of engineering blasting.
