| Abstract: | Relevant spectra figures are obtained by the transformation of practically measured wave into Fast Fourier Transformation(FFT).Through studying the spectra characteristics of blasting vibration,spectra characteristics of blasting vibration wave from foundation pit excavating are researched.The results are used to select a reasonable blasting method and explosives quantity,and help the anti-seismic design in parallel engineering blasting. |
