The base is also divided into two parts the heel and toe.
The counter forts act as tension stiffeners and connect the wall slab and the base to reduce the bending and shearing stresses.
Thickness of toe slab buttress not provided 8 of height of wall.
Thickness of counterfort 6 of height of wall.
Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall.
