Seismic Evaluation of Tall Reinforced Earth Retaining Walls

seismic responses of reinforced earth retaining walls have already been studied by many researchers. All the researches and constructions in practice have proven satisfactory performance of the reinforced walls. The effect of the height of such walls on the seismic response is of great importance, regarding the topography being located in a seismically active zone and the construction demand for tall retaining walls in a metropolitan capital. Therefore, in this research it was decided to study the seismic performance of tall reinforced retaining walls. First of all, a 17-m high reinforced retaining wall has been selected from literature as reference wall for analytical case study. Then, the wall has been modeled by establishing a numerical model for dynamic analysis using FLAC-2D, a two-dimensional finite difference software. Finally, seismic response of tall reinforced earth retaining wall was investigated through static and dynamic analyses.
