摘    要:基于现场实测爆破振动数据,根据爆破振动信号具有短时非平稳的特点,采用小波包分析技术对不同爆炸参量(爆心距、最大段药量和微差雷管段数)下产生的爆破振动信号进行小波包能量谱分析,获得了爆破振动信号不同频带的能量分布,研究了不同爆炸参量下的爆破振动信号能量分布特征,从爆破振动信号能量角度探讨了不同爆炸参量下爆破地震波的衰减规律,为研究爆破地震效应提供了一种新的分析技术。

关 键 词:爆炸力学    爆破振动    小波包能量谱    爆炸参量    能量分布

Abstract:According to the characteristics of short-time,non-stationary random signals,the wavelet packet energy spectra for the measured blasting vibration signals were investigated by using the wavelet packet analysis.These blasting vibration signals were produced in case of the different explosion parameters such as the distance of the measuring point from the blasting center,the maximum sectional explosive mass and the millisecond-delay detonator number.The energy distributions at the different frequency bands fo...
