Rankine's Theory of Active Earth Pressure

Assumptions:
(1) Soil mass is a  homogeneous, dry, cohesion-less and semi infinite.
(2) Ground surface is a plane which may be horizontal or inclined.
(3) Back of the wall is smooth and vertical
(4) Wall yields about the base.

Cases of cohesion less soil:
(a) Dry or moist back fill with no surcharge
(b) Submerged back fill
(c) Back fill with uniform surcharge
(d) Back fill with a sloping surface

To be continued ....
