【摘要】 为了探究影响爆破振动频率的各种因素,采用量纲分析方法研究了爆破地震波的产生和传播效应。基于小波包分析基本理论,将地震波中的低频波段进行细化,参照萨道夫斯基公式得到了爆破振动频率的预测方程,并进行了工程验证。结果表明,该预测方程的回归参数有较好的一致性,可以为爆破振动危害控制提供参考依据。更多还原

【Abstract】 Blasting vibration frequency is an important indicator for blasting hazard assessment,and exploring the various factors which effect the blasting vibration frequency have important theoretical value and engineering significance.Dimensional analysis method is used to study the generation and propagation problems of blasting vibration,and the frequency band was obtained by wavelet packet transform,on this base,the prediction equation of blasting vibration velocity similaring to the S formula is derived,and made an engineering validation.The research results put forward a reference on controlling the blasting vibration damage.更多还原
