The walls are used in a variety of applications se including right of way restrictions protection of existing structures that must remain in place.
Concrete block retaining wall design example.
Concrete masonry units concrete blocks manufactured to provide an attractive durable stable face to a retaining wall.
Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance.
Traditional retaining wall solutions can be expensive and restrictive for example cast in situ construction is slow and expensive to build and precast retaining wall panels are restricted in height.
Design procedure overview 3.
A concrete block retaining wall is the perfect solution to control erosion to eliminate a hard to mow slope to add a planting bed or to level an ideal patio area.
Chapter 14 retaining walls july 2020 14 7 14 1 introduction retaining walls are used to provide lateral resistancefor a mass of earth or other material to accommodate a transportation facility.
It is commonly used to separate.
Soil bearing and stability 8.
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.
Earthquake seismic design 7.
Concrete strength al ൯ne for an 10 thick wall with 5 10 and 2 5 clear to strength steel will only reduce the nominal moment capacity of the secti對on from 136 68 to 135 66 inch kips 尩 if the concrete strength decreased from 3 5 to 3 0 ksi.

In this example the structural design of the three retaining wall components is performed by hand.
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.
These systems are easy to install durable reasonably priced and available in a variety of colors and textures.
Forces on retaining walls 6.
Movement of the retaining wall.
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.
Integrate redi rock standard blocks with the entire family of redi rock products to create a seamless structurally sound solution for your next project.
Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.
These large wetcast blocks are like one ton lego blocks that interlock to create tall gravity retaining walls.
Available in block widths of 28 41 and 60 inches 710 1030 and 1520.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond.
Geotextile a permeable polymeric material which may be woven non woven or knitted.
