Attenuation Rules of Shock Wave in Air Blasting of Emulsion Explosive
摘要
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.关键词
