Retaining wall is not safe against sliding. Shear stress in the vertical stem is excessive. Shear force in the toe slab is more than that in the heel slab. Retaining wall is not safe against overturning.
Fail in both deflection and lateral stability Fail in deflection only Satisfy the requirements of deflection and lateral stability Fail in lateral stability only
The thickness of wall 1.5 times the thickness of wall 2 times the thickness of wall 3 times the thickness of wall
