A SET OF DESIGN CURVES WAS DEVELOPED FOR COMPUTING ACTIVE EARTH PRESSURES OF COHESIONLESS SOILS AGAINST RETAINING WALLS BASED ON COULOMBS THEORY. THE ASSUMPTIONS AND LIMITATIONS OF THE COULOMB THEORY MUST ALWAYS BE CONSIDERED WHEN USE IS MADE OF THE CHARTS. THE ASSUMPTIONS MADE BY COULOMB WERE THAT THE SURFACE OF FAILURE FOR A BACK-FILL OF COHESIONLESS WOIL WAS A PLANE SURFACE AND THE EFFECT OF CURVATURE OF THE ACTUAL FAILURE SURFACE CAN BE NEGLECTED. THE RELATIVE MOVEMENT BETWEEN THE RATAINING WALL AND THE SOIL MASS MUST BRING ABOUT A STATE OF ACTIVE EARTH PRESSURE FOR WHICH THE WALL FRICTION ANGLE IS POSITIVE. WHEN USED WITH UNDERSTANDING OF THE LIMITATIONS, THE DESIGN CHARTS OFFER A MEANS TO QUICKLY AND ACCURATELY CALCULATE EARTH PRESSURE AGAINST RETAINING WALLS.
