Experimental investigations of the compressibility of argillaceous soils subjected to underground explosions

The results of experimental investigations of the compressibility of argillaceous soils (loess loams, loams, and clays) subjected to underground explosions are discussed. The data concerning the deformation at the shock-wave front, and their comparison with data concerning residual deformations indicate that the viscoplastic soil properties strongly influence the soil compressibility for short-term loads originating from underground explosions. The conclusions which were previously drawn in [1] are qualitatively and quantitatively confirmed.
