| Based on results from a series of shaking table model tests on geogrid reinforced soil retaining walls, effects of material properties (i.e. pullout resistances, rupture strength and tensile rigidities) on seismic performance of reinforced soil retaining walls are discussed. Although the material properties of two geogrid models used in this study were largely different, residual displacements of wall facing were almost equal to each other. It is also attempted to obtain deformation characteristics of reinforced backfill soil from its dynamic responses and displacements of wall facing by assuming that the reinforced backfill would behave as one macro element. |
