Abstract The numerical analysis results from LIQCA are compared with the centrifugal testing results；and the response of earth and rockfill dam during seismic load is also studied. In general，the acceleration is amplified from the base of foundation to the top of earth and rockfill dam；and the predominant period and band width of soil acceleration are almost the same along the depth. The excessive pore water pressure is accumulated during the base shaking；and the final excessive pore water pressure increases with depth. This fact can also be explained by the stress path analysis from conventional cyclic triaxial testing result and LIQCA analytical results.
