In this example the structural design of the three retaining wall components is performed by hand.
In this example the structural design of the three retaining wall components is performed by hand.
Despite the many references a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found.
Let s take a fresh look and see how concrete interlocking blocks or more commonly known as concrete lego blocks can be used as the solution.
Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Over its intended service life other loads may also be applied to the structure.
Hence this attempt to condense simplify and compile information from many.
A retaining wall that relies solely on it s own weight to stand up is called a gravity wall allan block combines the basic engineering principles of setback leverage and total unit mass with simple mechanics to make highly stable gravity walls.
The coefficient of friction between the footing and foundation soil k 1 is 0 25 and the allowable soil bearing pressure is 2 000 psf 95 8.
Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.
Some of the advantages of using large precast concrete block systems for retaining structures include.
Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Two equations are developed.
For retaining wall applications the structure must be designed to resist the forces from the retained material acting on one side of the wall.
Setback sliding wedge.
The wedge is defined as the soil which extends beyond the failure.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
