Unconventional elastoplastic constitutive models such as the subloading surface model proposed by Hashiguchi can describe mechanical behavior of soils including cyclic loading behavior, realistically. Among them, the superloading yield surface model, which was proposed by Asaoka et al. is possible to predict the defamation behavior for various structured soils or densities of soils using a unique set of material parameters. In this article, the finite element analysis program in which the superloading yield surface model was incorporated is adopted for an analysis of wheel-soft ground interaction phenomena Soil compaction behavior for the various kinds of structured grounds due to the repetition of the rigid wheel travels is simulated by using the unique set of the material parameters for the structured ground. Moreover the influence upon soil compaction due to difference of layer thickness of ground is also examined here by the present analysis program
