Аnalysis of the changes in strength and deformation characteristics of loess solid mass as a result of dynamic loads

The necessity to provide stability of slopes, structures, and bearing capacity of rock
masses disturbed by blast loading depends upon the temporal and spatial changes in soil
parameters. Hence, we have analyzed the regularities characterizing a range of changes in loess
soil resulting from dynamic (namely, blasting) loads taking into consideration their
technogenesis under various conditions. The research territory is within the terraced right-bank
share of Dnipro city in its southern part. The territory is represented by a sedimentation mass
of the Anthropogene and Upper Pliocene deposits occurring on crystalline rocks and their
weathering crust (i.e. kaolin and granitic subsoil). They contain Poltava series sand; mottled
and red-brown clay; and loess-soil series. In this place, loess clay loam was sampled after blast
loading on the formation happened.
