For the last two decades, geosynthetic-reinforced soil retaining walls (GRS RWs) have been constructed for important facilities such as railways and highways. In order to achieve greater seismic performance, a new-type of geocell which have three dimensional structures, having straight longitudinal members with transversal members has been developed. In this paper, in order to investigate the seismic stability of the new-type of geocell reinforced retaining, a series of shaking table model tests was carried out by using the new-type geocell and geogrids as tensile-reinforcement in the sandy and gravelly backfills. Furthermore, an unreinforced retaining wall (T-shape) model was also tested for comparison. It was found that new-type geocell reinforced soil retaining wall model exhibited higher seismic performance than both geogrid reinforced soil retaining wall model and unreinforced retaining wall model.
