摘要

In this paper, characteristics of ground vibrations caused by rock motions in the channel beds were examined both experimentally and theoretically. The ground vibration was detected by three geophones installed in a straight line at the surface of the channel bed. The signals were discussed in terms of the frequency range, the phase speed and the spatial decay rate. The sphere-packing model of granular rocks proposed by Duffy & Mindlin (1957) was also used to estimate the theoretical phase speed of the ground vibration and compared with the experimental data. Our results showed that the sphere-packing model of granular rocks provides a rather reasonable esti mation of propagation speed of the ground vibration.
