【摘要】 结合武汉新港阳逻集装箱码头水下钻孔爆破工程,通过现场数据监测,针对爆破振动的特征,采用Matlab小波分析软件,对实测爆破振动信号进行能量分析,得到不同频带上爆破振动信号的能量分布。基于小波包频带能量分布,探讨了爆破振动信号各频带振速与能量分布关系。更多还原

【Abstract】 In this thesis,through the field data monitoring of Wuhan Yangluo Newport Container Terminal underwater drilling blasting for blasting vibration characteristics,based on wavelet analysis software of Matlab,the energy of the monitoring blasting vibration signals was studied by means of the wavelet packet analysis,which had high resolvability and localization,and the energy distribution of blasting frequency domains was obtained.Based on wavelet energy method,discussed the frequency domain velocity and energy distribution relationship based on the different blasting vibration signals and a single blasting vibration signals.更多还原
