Summary:In order to study the acceleration distribution of high rock-fill dam, the dynamic response of homogeneous earth-rock dams over 100m were analyzed with three dimensional (3D) finite element method considering the height and slope of the dam, aspect ratios of river valley, dynamic shear modulus, peak acceleration and seismic waves. The results show that the 3D effect of dynamic response is apparent. The acceleration is significantly enlarged in the middle of river bed of the dam over 4/5 height and recommended distribution of the acceleration by the current code is inconsistent with response characteristics of the high dam. The reinforcement zone is suggested based on the calculation results of high dam.
