Seismic Analysis of Reinforced Earth Wall Along With Soil Structure Interaction

Retaining structures are susceptible to failure during strong earthquakes and are damaged frequently so it is important to study the reinforced earth wall under the seismic loading. Reinforced earth wall is retaining wall with panel and reinforcement as steel strip, geogrid or geosynthetics. Lot of research is carried for its static stability but very little work has been carried out for its stability in dynamic condition. The effects of soil properties, earthquake motions, and reinforcement layouts are issues of major design concern under earthquake loading. Reinforced earth wall that support dry cohesion less backfills form a major group of the earth retaining structures. These walls fails under the seismic loading and its stability is affected which has led to implementation of Soil Structure Interaction in reinforced soil wall. The proposed work is concerned mainly with the seismic behavior of the reinforced earth wall considering soil structure interaction. The objective is to examine the effect of soil structure interaction in seismic behavior of reinforced earth retaining wall. In these the seismic performance is studied in the finite element program Plaxis.
