摘要
采用小波分析方法对工程爆破引起的地震动信号能量进行了分析,得出了小波系数与信号能量之间的关系,并用工程实测数据进行了分析,验证了文章中理论推导所得的结论。作者认为,由于小波分析的时-频特性。
With the help of the wavelet analysis, the relationship between the energy input to the structure and the wavelet coefficients is indicated. It is concluded that the energy of the earth vibration signal is proportional to the square of the wavelet coefficients deduced from acceleration data transformed by the wavelet transform under pointed level.
