Abstract

The wave propagation analysis revealed that the low-frequency pendulum wave propagating in a 2D block medium with periodic structure due to the action of local impulse has a two-wave structure. The shape of such wave depends on its propagation direction. Modeling the blast-induced seismic wave propagation in a two-layer block rock mass with the weak upper layer and stiff lower layer showed that the far distant point from the wave excitation source is first reached by the small amplitude pendulum wave running in the stiffer lower layer and then by the delayed maximum-amplitude wave propagating in the upper layer.
