This study seeks to characterize the dynamic behaviour of each section and to understand the performance of the interface using centrifuge model test and numerical analyses. The model test was verified by the comparison of the test results with those of numerical analyses, and the natural frequency for the composite dam with concrete-rockfill was proposed as like the same centrifuge model test and numerical analyses.
