8 Assumptions of Coulomb’s Wedge Theory
Following are the 8 assumptions of coulomb’s wedge theory or coulomb’s wedge failure theory
1. The backfill is dry and cohesionless.
2. The backfill is also homogenous and isotropic.
3. The backfill surface is a plane surface and can be inclined.
4 The back of the wall can be inclined.
5. The failure surface is a planner surface which passes through the heel of the wall.
6. The backfill is elastically non-deformable but maybe breakable.
7. The position and the line of action of the earth pressure are known.
8. The sliding wedge is considered to be a rigid body and the dearth pressure is obtained by considering the limiting equilibrium of the sliding wedge as a whole.
