摘要(Abstract):

在小波、小波包的理论基础上,结合某市城市建设中基岩爆破中振动监测数据,采用这两种方法对同一爆破振动信号在信号去噪、对细节信号的处理、信号的分解与重构方面将两种方法的应用和效果进行了对比。分析表明,采用小波包技术研究爆破地震波信号比小波分析技术有更强的灵活性,能更加完整地反映爆破振动信号的特征。
Regarding the vibration data monitored from rock blasting in urban construction of a certain city,the paper compared the application and results of two ways of analyzing on the same blasting vibration signal in terms of signal denoise,detail signal processing and signal decomposition and reconstruction based on the wavelet and wavelet packets theory respectively.The comparative analysis showed that the use of wavelet packets technology for studying blasting seismic signal was of more flexibility and could make more completed reflection of the characteristics of blasting vibration signals compared to wavelet analysis.
