Retaining structures are designed and constructed to resist lateral pressure of backfill material, generally soil, when there is a desired change in ground elevation that exceeds the angle of repose or to retain the backfill. The retained backfill material exerts pressure on the structure which when exceeds leads to structural failure. Thus, design considerations are of extreme importance and all factors that influence the magnitude of earth pressure must be thoroughly examined. The present study deals with the evaluation of active earth pressure for cohesion-less soil under different boundary conditions, dealt generally in practice. Various combinations of soil parameters like ?, ?, ?, height of retaining structures (H) are studied within practical ranges to evaluate their impact on active earth pressure. The magnitudes of pressure under various cases are analyzed graphically using Culmann’s graphical solution and compared with those obtained using Elastic Theory which denotes the decrease in active earth pressure with the increase in load distance (0.3H, 0.5H, 0.7H) from the face of the wall.
