Retaining wall reinforcement design example.
Retaining walls example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of 30.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
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.
Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.
Two equations are developed in this section for determining the thickness reinforcement required.
The following design example briefly illustrates some of the basic steps used in the allowable stress design of a reinforced concrete masonry cantilever retaining wall.
The base is divided into two parts the heel and toe.

Soil mechanics simplified 4.
Assuming that the allowable bearing pressure of the soil is 120 knm 2 the.
Assume level backfill no surcharge or seismic loading active earth.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
