摘要
以快速傅利叶变换FFT为基础 ,开发了频谱分析的应用软件 ,对各种规模的台阶爆破进行了频谱分析 ,得出了一些有益的结论。同时分析了地震波的频率对建筑物的影响。
On the basis of rapid Fourier transformation FFT,an application software for frequency spectrum analysis was developed.It was used to make the frequency spectrum analysis of bench blasting of various scales and some useful conclusions were made.The effect of the frequency of seismic wave on buildings was also analysed.
