Residual Settlement Evaluation of Rockfill Dam under Centrifuge Shaking Table Test by Watanabe and Baba Method

Abstract

Recently seismic deformation of earth structure has been evaluated by comparing with allowable deformation maintaining on the function. This study simulates the observed settlement of centrifuge shaking table test of rockfill dam by Watanabe-Baba method which expand Newmark method to FEM analysis. As a result, Watanabe-Baba method can simulate adequately the deformation of loose case up to the settlement larger than 0.5% of dam height or 1m, however it estimates the settlement smaller than observed settlement of dense case.
