Dynamic deformation characteristics of rockfill materials such as shear moduli and damping ratio must he known to analyse the behavior of rockfill dams during earthquakes. Comparative studies on deformation characteristics at small strain were examined for the Miho Dam. First, the S-wave velocities with depth obtained from shear moduli in cyclic loading laboratory tests were compared with the in-situ S-wave velocities. Secondly, the response analyses of six observed earthquakes were carried out, and the relationship between shear modulus and shear strain by the analyses was compared with the relationship by laboratory tests. Then, the laboratory test results agree well with the field results. Lastly, the radiation damping ratio due to the response analyses of observed earthquakes decreases according to the increase of the natural frequency, as is in good agreement with the studies by other researchers. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
