Physical and numerical analysis of reinforced soil wall on clayey foundation under repetitive loading: effect of fineness modulus of backfill material

This paper investigates the relative seismic effect due to backfill materials of geotextile-reinforced wrap-faced soil walls by performing shaking table tests. Two types of backfill materials were used containing higher and lower fineness modulus (FM). Sinusoidal harmonic motions and two earthquake waves (1989 Loma Prieta earthquake and 1995 Kobe earthquake) were applied to the model to evaluate the seismic performance. Results of the shaking...
