||A series of centrifuge model tests was conducted to simulate the dynamic
response of reinforced earth embedment. The variables considered in the
centrifuge testing program were the reinforcement tensile strength,
reinforcement spacing, reinforcement length, embedment height, and slope
inclination. The main objectives were to investigate reinforced earth embedment
in different reinforced type, and geometry.
According to model test results, the following conclusions are made：
1. For a 4m-high embedment, the predominant frequency is about 10Hz, for an
8m-high embedment, the predominant frequency is about 5.7Hz, and for a
12m-high embedment, the predominant frequency is about 4.5Hz, which
means predominant frequency had a significant association with the height of
2. There are some acceleration attenuation phenomenon occurs at 1Hz event
and related to the significant movement of the embedment.
3. For all 8m-high embedment, model conducted with the reinforcement tensile
strength 112kN/m and 62.5kN/m performed very well under seismic loading.
4. According to the rupture point of reinforcement we can draw a failure surface,
the failure surface it similar to a circular failure surface.
