This note describes the results of analyses of calculating circular tank embedded in an isotropic homogeneous elastic half-space as introduced by Vlasov and compared with analyses of the same tank in discrete soil as introduced by Winkler. The study made an attempt to see how not so widely used theoretical model of soil can influence soil-structure interaction. Based on the finding it was revealed that Vlasov’s elastic subsoil hypothesis is in advantage over Winkler’s model. The theoretical computations were validated by comparing them with the tested model research in very similar conditions to the natural environment. The data from model testing in dry sand and wet sand were collected in 1979.
