Abstract

The article presents the model study into determination of block medium structure parameters by the seismic sounding method. The modeling was performed on a fragment of a brick wall. The wall was subjected to impulsive loading, and oscillograms of vibration accelerations in certain bricks were recorded. The velocities and spectral structure of waves were determined from the experimental data. The ratio from the earlier one-dimensional experiments, which connects the velocity of a low-frequency pendulum wave, the frequency limiting the wave spectrum and the longitudinal dimension of a block, holds true on the two-dimensional model of the block medium represented by the brick wall. The research findings allow determination of sizes of characteristic blocks in rock mass by the data of seismic sounding.
