A series of centrifuge shaking table tests are performed to study the seismic behavior of geosynthetic reinforced earth(GRE) embankments. From the test results, for an 8-m-high GRE embankment, the natural frequency is found to be about 5.7 Hz and has no significant relationships with the reinforcement material, the reinforcement arrangement, or the facing batter. The amplification of the acceleration increases with increasing elevation and with increasing frequency of the input motion. At the same elevation, the amplification inside the reinforced earth zone is found to be larger than that inside the retained soil zone. |
