Abstract: This paper presents a model of cyclic loading based on soil plasticity model homogeneous materials (Plastic-Displacement, P-D). The presented model analyzes the phenomenon of cyclic uniaxial compression soil samples in three stages of loading. As a soil analyzed in the paper was chosen sandy clay stabilized with hydrated lime also where previously specified physical characteristics of the sandy clay. The results of the studies and the results of calculations using the model of P-D were presented. Also compare of the results obtained by the model with the results of tests were conducted. The aim of this study was to check on the need Eurocode 7 to place the design approach applicable to cyclic loaded soils and propose the P-D model as a model appropriate for cyclic loading. Obtained results of chemically stabilized material show the applicability of plastic-displacement as well as for natural soils.
