Abstract

The attenuation characteristics of elastic wave propagation in granite，marble，red sandstone and limestone were studied by a PCI–2 system though the broken lead test. The results showed that：the amplitude and frequency of the elastic wave signals on the four kinds of rocks are decreasing with the increased source distance. On granite and red sandstone，the attenuation of amplitude and centroid frequency are obviously characterized by stages，the attenuation coefficient is larger in rapid attenuation stage and smaller in slower attenuation stage，correspondingly，the peak frequency is higher in rapid attenuation stage，and dramatically reduced in slower attenuation stage. However，the attenuation of amplitude and centroid frequency on marble and limestone is relatively moderate，and the peak frequency maintains at 120 kHz. By analyzing the microstructure of four kinds of rocks and their attenuation characteristics，it is found that the most important factor causing the attenuation of the elastic wave is the tightness of the mineral particles in rock，and secondly the development degree of internal structure is another factor influencing attenuation. Furthermore，the quality factor Q of different rock is highly related with its wave impedance，the lower wave impedance rock has smaller Q value，corresponds to higher wave attenuation.

Key words： rock mechanics elastic wave attenuation characteristics quality factor wave impedance
