| Abstract: | Results of an experimental and theoretical analysis of Kol'skii's method for dynamic tests of soft soils in an elastic casing
are presented. The model proposed by S. S. Grigoryan for a plastically compressible medium with parameters determined in shock-wave
experiments was used as the model of a soft soil. The high-rate deformation of the soil was simulated using a modified “Dunamics-2”
program package. The numerical calculations performed showed that the compliance of the casing and friction practically do
not influence the measured characteristics of the soil and the basic premises of Kol'skii's method are adequate for soft soil
too.
