In order to clarify analytically mechanical behavior of sand ground-structure system under cyclic central or eccentric loading condition, a series of FEM analysis and model test were performed. In this study, a technique of analysis for lateral deformation of sand deposits is proposed. The characteristics of elastic modulus of ground were detailedly investigated in advance and were quantifed. The results obtained from this analysis, which is based on the change in rigidity of ground, are also compared with those of the model test. It was found that the behaviors of settlement and lateral flow deformation can be simulated by means of FEM analysis with changes in the elastic modulus of ground.
