ANALYSIS OF REINFORCED EARTH WALL

Abstract

In the present work displacement mechanism and behavior of reinforced soils are studied under different soils and loading condit ions. A comparative study of init ial load-sett lement relationship, distr ibut ion of axial and shear forces in the reinforcement and stress distr ibution in reinforced soil structures is presented. Finit e element analysis is carried out using commercial software PLAXIS version 8 for this problem wit h different soil condit ions. The results are compared and reported in this dissertat ion. Behaviors of reinforced soil structures under different condit ions are investigated using PLAXIS version 8. Effect of the soil reinforcement is shown through the improvements in the load-deformation relations, the reinforcement axial force, stress distr ibution and displacement in the soil mass. The effect of spacing of geogrids is explained through displacements variation. Wall displacements and strain distr ibut ion along geogrid layers are observed. Effe...
