Civil Engineering : Soil Mechanics - Quiz(MCQ)

Coulomb's wedge theory assumes that_________.

A)

back fill is dry, cohesionless, homogeneous and isotropic

B)

slip surface is the plane which passes through the heel of the wall

C)

position and direction of the resultant earth pressure, are known

D)

All of the above

Correct Answer : All of the above

Explanation : * back fill is dry, cohesionless, homogeneous and isotropic
* slip surface is the plane which passes through the heel of the wall
* position and direction of the resultant earth pressure, are known
* sliding wedge itself acts as a rigid body and the value of earth pressure is obtained by considering the limiting equilibrium of the wedge
