Which of the following is an incorrect assumption of Coulomb’s Wedge Theory of Earth pressure?
1
The back-fill soil is dry, cohesion less, homogeneous, isotropic and ideally plastic material.
2
The slip surface is a plane surface that passes through the heal of the wall.
3
The sliding wedge itself acts as a rigid body and the value of earth pressure is obtained by considering the limiting equilibrium of the sliding wedge as a whole.
4
The resultant earth pressure on the wall is inclined at an angle (90°+ δ) to the normal to the wall. where δ is the angle of friction between the wall and backfill.
