Abstract

Based on computer simulation by the movable cellular automaton method we study theoretically the effect of vibration on the response of an interface fragment in a block medium in a complex stress state. It is shown that changes in the local stress level cause directional changes in response parameters of the system under vibration. This opens up the way to developing new methods of local stress level evaluation on active interfaces in block media with faults. In this connection in the paper consideration is given to the problem of inducing relative displacements of loaded fragments of blocks along the interface by variable duty ratio pulse trains. It is shown that the efficiency of such action depends first of all on the time of pulse energy release and depends weakly on the duty ratio.
