• Abstract: Report presents the results of centrifuge model experiments and numerical analyses of seismic response of retaining structures with cohesive backfill. The experimental results show that the static and seismic earth pressures increase linearly with depth and that the resultant acts at 0.35H-0.4H, as opposed to 0.5-0.6H assumed in current engineering practice. Overall, the results also show that typical retaining walls designed with a static factor of safety of 1.5 have enough strength capacity to resist ground accelerations up to 0.4g.
