Abstract

In this paper the dynamic deformation stages of soils under cyclic loading and the major factors affecting the shear modulus of soils are analyzed. The in-situ measurement of surface wave by larger energy source to obtain the shear modulus of the ground is described. On considering the important effect of shearing dilatancy on shear modulus of sandy soils, a modified formula is proposed. For typical soils, the axial strains under cyclic loading are determined either for estimating shear modulus or for the deformation analysis in design.
