However the active earth pressure condition will be reached only if the wall is allowed to 'yield' sufficiently. The amount of outward displacement of the wall necessary is about 0.001H to. 0.004H for granular soil backfills and about 0.01H to 0.04H for cohesive backfills.
11 Mar 2010 Coulomb theory provides a method of analysis that gives the resultant horizontal force on a retaining system for any slope of wall, wall friction, and slope of backfill provided This theory is based on the assumption that soil shear resistance develops along the wall and failure plane.
CE352A. Dr. Rajesh Sathiyamoorthy, IIT Kanpur. Coulomb's Earth Pressure Theory – Graphical Method Culmann (1875) developed a graphical solution of Coulomb's Passive earth pressure. The Culmann solution provides us with only the magnitude of the active force per unit length of the retaining wall—not with the point
Rankine Earth Pressure theory and Coulomb's Earth Pressure theory. Firstly we will learn rankine earth pressure theory (the most important) and then coulomb earth pressure theory. Rankine Active Lateral Earth Pressure. This theory is based mainly on the assumption of neglecting friction between the soil and the wall,

The Coulomb theory provides a method of analysis that gives the resultant horizontal force on a retaining system for any slope of wall, wall friction, and slope of backfill provided. The slip surface is a plane surface which passes through the heel of the wall. The wall surface is rough.
Coulomb's earth pressure theory. 2. Rankine's earth pressure theory. The first rigorous analysis of the problem of lateral earth pressure was published by Coulomb in (1776). Rankine (1857) proposed a different approach to the problem. These theories propose to estimate the magnitudes of two pressures called active earth
