Seismic stability of reinforced soil wall under different seismic waves using centrifuge shaking table tests

This paper describes effects of input seismic wave properties on seismic stability of reinforced soil wall. For that purpose, the centrifuge shaking table test series was conducted with different waves. In the centrifuge test, behaviour and residual deformation of reinforced soil wall during earthquake were compared. As a result, it was found that acceleration response of the wall was almost the same along the wall height and deformation did not occur until the active acceleration exceeded the particular value. After the acceleration reached to that value, displacement of the model wall increased with shaking. Moreover, The relationships between shear stress and shear stiffness were determined by using the acceleration records. The shear modulus increased with shaking because the tensile stress was induced to the geogrid due to the deformation.
