How do you reinforce a retaining wall?
The wall can be strengthened by transferring some of the shear force to the base where the wall meets the ground. This can be done by either extending the footing of the base or placing concrete to thicken the base. Installing anchors or tiebacks is another option for extra strength.
What is the principle of cantilever retaining wall?
Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage. It has much thinner stem and utilize the weight of the backfill soil to provide most of the resistance to sliding and overturning. Cantilever retaining wall is the most common type of earth-retaining structure.

What is maximum height limit of cantilever wall?
Cantilever retaining walls are found best up to a height of 6m. For greater heights earth pressure due to retained fill will be higher due to lever arm effect, higher moments are produced at base, which leads to higher section for stability design as well as structural design.
Does retaining wall need reinforcement?
Segmental retaining walls (SRWs) are designed to be used as a gravity wall either with or without reinforcement and can have heights in excess of 40′. SRWs are modular blocks made from concrete that are often dry stacked without mortar.
How do you stop a retaining wall from failing?
Saturated Backfill Prevention tip: To prevent saturated backfill behind a retaining wall, the surface of the backfill needs to be properly graded to direct water away from the wall. If this is not possible, drainage channels need to be installed adjacent to the wall.
Can a retaining wall be a shear wall?
Retaining walls are vertical cantilever structures, while shear walls are connected to floor slabs at top and bottom of the story. Retaining walls exhibit stability problems such as sliding and overturning, whereas shear walls are part of a building system except for buckling they don’t exhibit stability problems.
What is the maximum height of retaining wall?
Most retaining walls, whether load-bearing or not, average between 3 and 4 feet in height. As a general rule, you do not want to build any sort of structure over 4 feet in height without including some type of structural support within.
How much weight can a retaining wall hold?
Even small retaining walls have to contain enormous loads. A 4-foot-high, 15-foot-long wall could be holding back as much as 20 tons of saturated soil.
