Abstract

Effect of external compression on seismic waves in rock mass was tested on one-dimensional models of block media subjected to impulsive loading. It is shown that a low-frequency pendulum wave appears at the shock wave head as a result of dispersion. The pendulum wave parameters are governed by the mass of blocks and by the yielding properties of block interfaces. External compression increases stiffness of block interfaces, which leads to an increase of the wave velocities and to a change of the wave spectra. The model experiments tested the possibility of external compression assessment from the parameters of pendulum wave spectra.
