岩石集中式双药室爆炸能量计算

Galculatioan on the Explosive Energies of Double Concentrated Changes in Rock Blasting

将岩石爆破药包间相互作用影响纳入到爆能分布的计算中，因而修正了目前仅由单一药包估算爆炸能量的方法。对单药宝空腔能现有计算式也提出了相应修正。药包间作用使岩石运动速度场和应力场产生变化，致使爆炸抛石和冲击波能量有所改变。

By considing the interaction among explosive charges, a modified method is presented to determine the redistribution of eXPlosive energies of the charges, which also refer to a modificationof the existing formula for the evaluation of the cavity energy from single charge. The interactionamong the caharges cause some changes of the fields of the rock velocity and stress, which lead tocorresponding changes of the throwing-stone and stress wave energies.
