This study aims to clarify analytically mechanical behaviors of a sand-structure system subjected to static and cyclic loadings.In particular, the settlement-lateral deformation behaviors of the ground bearing a structure are focused.A series of FEM analysis based on Mohr-Coulomb formulas with non-associated flow rule was carried out to accomplish the purpose.The analysis results obtained were detailedly compared with those of the model static and cyclic tests performed on the two-dimensional soil box.On the basis of these results, the applicability of FEM analysis to evaluate the deformation behaviors of the ground-structure system was made clear.
