| Abstract: | Based on the attenuation information(waveform and spectrum) in the seismogram,the seismic quality factor Q can be calculated for the rock mass.This paper presents some typical methods to compute the Q value to evaluate the rock mass quality.The methods include amplitude,rise-time, spectral ratio,and centroid frequency shift.The paper gives the principles of these methods,and discusses their stability and applicability. |
