Abstract
Earthquakes tend to cause damage to geogrid reinforced soil wall and appropriate repair method should be decided after the event. This paper focuses on the assessment of seismic stability of geogrid reinforced soil walls using a vertical wall and inclined wall to simulate initial damage. The models were subjected to a stepped sinusoidal wave using a shaking table until full failure occurred. Wall horizontal displacement and shear strain distribution in all models increase with base acceleration and with tilting angle. Slip lines observed in the backfill of the model agree with two-wedge method and slip lines obtained using mobilized pullout resistances are almost similar to those observed in the experiments.
