Prediction of stress-strain in reinforced earth retaining wall

The Stress-strain relationships of reinforced earth retaining walls, using Netlon geogrids as reinforcement and ferrocement panels as facing elements, have been presented. The backfill material used was river sand. Model retaining walls for different combinations of vertical spacings of reinforcement were constructed and their behaviour were observed. The experimental set up was simulated by a two dimensional F.E.M model. A comparison of the stress-strain relationships, obtained from experimental and from the model analysis, have been presented. It has been concluded that the F.E.M model is quite satisfactory for the prediction of lateral strain and vertical settlement of the geogrid reinforced earth retaining wall.
