摘 要: 为评价膨胀能Eb在破岩过程中的作用,进行了爆炸应力波的测定实验,研究了冲击能(Es)与膨胀能(Eb)分配比值的变化对爆炸应力波峰值的影响。实验结果表明,随着Es/Eb比值的增大,原生爆炸应力波的峰值随之增大,而次生爆炸应力波的峰值则相应减小。 To evaluate the function of Bubble energy(Eb) in the rock fragmentation process,a test on measuring explosive stress wave was made and the effect of the change in the ratio of shock energy(Es) to Eb on the peak values of explosive stress waves was investigated.The test results showed that,with the increase of the ratio of Es to Eb,the peak values of the primary explosive stress wave increased while that of the secondary wave decreased.
