抄録: Characteristics of the shear strength and compressional deformation of sand having the same compaction method and the same initial density are studied by using oedometer and direct shear appratus, when sand is subjected to various stress history on shear stress and normal stress on the shear plane. In the compressional deformation characteristics, by initial compressive stress σ。 is repeated loading sand structure change to the stabilized particle arrengement corresponding to σ。, as the results stress history effect on the compressional deformation characteristics of sand. And the compressional deformation of sand is approximately elastic in the rangeσ≦σ。. On the other hand, shear strength of sand not increase by repeated loading of normal stress on the shear plane (=initial compressive stressσ。), but increase by repeated loading of shear displacement or shear stress on the shear plane. And optimum repetitional shear displacement or shear stress on the shear plane, which effect on increase in shear strength of sand are exist.
