Abstract A parametric study using finite element method of analysis was undertaken to investigate the behavior of an anchored earth wall system supporting clay backfill. In this paper the effects of stiffness of reinforcing tendon, elastic modulus of backfill soil, elastic modulus of retained soil and anchor size on the behavior of the wall system are presented. It was observed that deformation of wall decreases with increasing stiffness of reinforcement and above certain value of stiffness it has no effect on deformation. Most important finding was that coefficient of lateral earth pressure depends on the stiffness of reinforcement. For extensible reinforcements (axial strain > 1%), coefficient of lateral earth pressure is less than that of an active pressure condition. Deformation decreases with increasing stiffness of backfill and retained soil. Anchor force also decreases with increasing stiffness of backfill but remains constant with the variation of stiffness of the retained soil. It was also concluded that anchor block may be designed for a factor of safety of 2 or more.
