on a unit-length of wall;w = Weight of a unit-volume of the earth;h = Height of wall; (f) = The angle of repose with the horizontal—that is, the angle at[which that kind of earth will remain without further sliding. Then, when the upper surface of the earth is horizontal, we have theequation: E =… … Fig. 66. Pressure on Retaining Wall. An inspection of Equation 6 will show that the pressure E is greaterfor small values of 96. The angle of repose for various materials isnot only variablefor different gradesof material, but isvariable for thesame grade of ma-terial under variousconditions of…
