Abstract:
We study mechanical conditions under which the effect of anomalously low friction in block media from various geomaterials, which was revealed by the authors, is realized. It is shown that the maximum transverse (horizontal) displacements of the blocks occur only in the case of canonical coordination of the delay intervals between the vertical and horizontal pulse effects on the block system and the working block, respectively. In the case of static horizontal actions on the working blocks, significant displacements of the latter occur at absolute values of these actions, which are much smaller than the corresponding friction forces.
