In this research, a series of centrifuge model tests and dynamic response analyses were conducted to elucidate the impact of a composite structure comprised of a reinforced earth-pressure-resistant technique, using both masonry blocks and the reinforced earth method, which was installed at the slope toe end of an aged reservoir. The purpose of the study was to evaluate the seismic response of the embankment. The experimental tests included shaking table tests that were performed on an unreinforced embankment as well as a masonry block reinforced embankment, both in a water storage condition. The dynamic behavior of the embankment, as well as the propagation of slip failure, were compared and verified. Through the use of elasto-plastic dynamic response analysis, using the finite element method, the location of the slip surface, the settlement of the embankment and the dynamic response characteristics, as obtained experimentally, were examined to clarify the effects of the counter measure structure. The results indicate that the implementation of masonry blocks and the reinforcement installed behind them greatly improve the stability of the slope of the embankment, suppress the shear failure of the upper part of the embankment, and effectively prevent overall deformation of the embankment.
