Determination of the damping ratio by multi-channel spectral analysis of seismic downhole data

Soil dynamic parameters such as the damping ratio are of major interest in earthquake engineering. We’ve currently published a publication which comes back to a relationship between attenuation and velocity dispersion of body waves which replaces the measurement of the amplitude characteristics of seismic signals by a frequency dependent velocity function. The implementation of this method ...
