Abstract
On dynamic analyses of rockfill dams, dynamic deformation characteristics of rockfill materials such as shear moduli and damping ratios must be known to make analysis more accurate. In this study, large-scale cyclic triaxial tests were carried out using rockfill materials of actual dams, and the results were compared with the dynamic deformation characteristics obtained by in-situ geophysical explorations and response analyses of earthquake motions observed at dams. Furthermore, the radiation damping ratio was estimated from response analyses and laboratory tests, and then the frequency and strain dependency characteristics of the radiation damping were evaluated.
