Abstract: Finite element dynamic response analysis has been the most practical and valuable tool for use in the examination of seismic stability of fill-type dams. To make FE-solutions more accurate and reliable, extensive studies are still required on the dynamic properties of embankment materials and foundation soils. In this paper, some discussions are given on the dynamic deformation characteristics, especially dynamic shear modulus of deformation, of compacted fill materials. An attempt is made to propose some useful formulae of estimating dynamic shear modulus through static shear strength. Main results are summarized as follows : 1) Characteristics of dynamic shear modulus of compacted soils depend on the pre-compression effects. 2) Unconfined compressive strength can be a practically useful measure to represent these pre-compression effects. 3) Dynamic shear modulus of compacted soils can practically be estimated through their static shear strength.
