【摘要】 为评估装药爆炸对地下结构毁伤情况,采用AUTODYN程序,对地下目标结构装药爆炸的爆炸波传递过程进行了三维数值模拟,分析了不同装药量下爆炸波的传播情况,给出了地下目标不同位置处的冲击波超压等参数,在此基础上,结合北约NATO规范和美国DoD规范,对爆炸的影响范围进行了初步分析与评估。更多还原

【Abstract】 In order to study the blast wave propagation generated from an underground explosion and its effect on structures and personnel in the vicinity, numerical simulation is carried out to estimate overpressure.A three dimensional model is established to estimate blast wave propagation inside the underground structure.The blast wave intensities inside the structure,at the every exit of the effect are estimated. The numerical results of overpressure are compared to the respective allowable criteria for structure and personnel protection given in the USA DoD manual and the NATO standard.The personnel in a underground structure blasting scenario is determined.更多还原
