Abstract: Nonlinear dynamic response behaviours of rockfill dams are investigated on the basis of numerical computations by the finite element method. Analysis is made on a hypothetical actual size rockfill dam which is subjected to both harmonic excitations with different magnitudes in acceleration ampltiude and frequency and actual earthquake disturbance. It is recognized that the distributions of response accelerations and shear strain developed in the embankment are almost horizontal at resonant, which are similar as those represented by the shear beam theory. Also is noticed that large vertical acceleration may develop along both sides of slopes even if the input base acceleration is horizontal when its frequency is higher than the eigen frequency of the embankment. Concerning the applicability of linear procedure for the response analysis of fill-type dams, it is emphasized that nonlinear behaviours of embankments can be explained by the linear analysis procedure provided that reasonable shear strain level is assumed.
