Original Abstract

The following possibilities of reduction of dimension in the computational analysis of strain and stresses transferred to the subsoil massive are available: i) coming from the effective subsoil model by Koář & Němec (1989), based on the assumptions of the Pasternak’s model (1954), where the pair of material parameters of a surface model is evaluated from the energy equivalence, ii) reducing a large sparse matrix of soil massive stiffness to a smaller one, using Schur’s complement technique. In both cases i), ii) the steady-state analysis is decisive: inclusion of more complicated combination of loads can be performed without repeated computations.
