THE DEFORMATIONAL AND THE ANOMALISTIC WAVE-VELOCITY CHARACTERS FOR THE ADHERED ROCK-SAMPLES LOADED

The experiments that the complete and adherent rock-samples are loaded with different rate under uniaxial compression have made. The deformation and the anomalistic wave velocity feature are observed. It was found that the difference between the complete rock-samples and the adhered rock-samples in the strength, deformation, wave-velocity anomaly etc. are existed But the similarity in the duration of wave-velocity anomaly, the attenuation ratio of the coda wave and the amplitude spectrum character etc. between the two were also existed.
