Cantilever retaining wall is the most common type of earth retaining structure.
Cantilever retaining wall reinforcement design.
It is constructed of reinforced portland cement.
These design methods are discussed in detail in allowable stress design of concrete masonry tek 14 7a and strength design of concrete masonry tek 14 4a refs.
The base is divided into two parts the heel and toe.
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 are usually of reinforced concrete and work on the principles of leverage.
It is the length from face of the wall stem to rear end of the base slab which includes the thickness of stem.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
Assuming that the allowable bearing pressure of the soil is 120 knm 2 the.
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.
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.
Recommended stem designs for reinforced cantilever retaining walls with no surcharge are contained in tables 1 and 2 for allowable stress design and strength design respectively.
