Deformation of soils are composed of shear and volumetric deformations. Volume change are caused by both shear stress and hydrostatic stress and they are respectively called dilatancy, consolidation. In granular soils such as sands and gravels, volume change caused diviator stress Cshear stress), i.e. dilatancy, is important to understand a stress-deformation relation of granular soils. In this paper, firstly, shear deformation and consolidation are separately studied in mean principal stress constant test and isotropic compression test. Secondary, supposing that deformations caused stress change are expressed as summation of their deformations, deformation characteristics of dense sands having a positive dilatancy such as principal, strain, volume change, principal strain ratio, coefficient of earth pressure at rest under triaxial compression are studied.
