Cantilever retaining wall reinforcement design.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
For preliminary design considerations the length of heel slab is taken as h k a 3 as according to pillai and menon reinforced concrete design 2011.
Cantilever retaining wall is the most common type of earth retaining structure.
The base is divided into two parts the heel and toe.
It is constructed of reinforced portland cement.
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.
Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Assuming that the allowable bearing pressure of the soil is 120 knm 2 the.
It is the length from face of the wall stem to rear end of the base slab which includes the thickness of stem.
Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
