| This paper discusses the effect of the damage level on the seismic stability of a geogridreinforced soil wall with a divided facing panel system based on the results of 1g tilt-table tests. The model had a height of 810 mm､ length of 1650 mm､ and width of 500 mm. The fill material was sandy soil､ and the geogrid was connected to the divided facing panel. The test included a pre-tilt stage to give damage to the model､ an un-tilt stage to return to the initial condition from the pre-tilt condition､ and a retilt stage to observe the ultimate limit state of the damaged model. In a series of tests､ the effects of three damage levels were investigated by changing the tilting angle in the pre-tilt stage. The models showed elastic behaviors in the un-tilt stage. In the re-tilt stage､ both the facing displacement and reinforcement strain increased rapidly after the tilting angle reached its maximum value in the pre-tilt stage. |
