摘要
本文以爆破振动幅值与频谱的分析为依据,研究和总结了爆破介质质点振动速度传播的特征,探讨了起爆顺序、装药结构、爆破近区的破坏与振速的关系,岩体的动力反应以及能量随频率的分布特征等问题。
According to the analysis of amplitude and spectrum of blasting vibration, the paper studied the characteristics of vibration velocity propagation of medium particle, the relation of blasting sequence, charging construction and damage near blasting area with vibration velocity. In addition, dynamical reaction of rockmass and energy distribution in accordance with frequency were also discussed in the paper.
