A retaining wall can be made up of many components. Listed below are the main ones. The
base slab is the first component. A base slab supports a cantilever wall and tapers to it at the
top. A key can be used to increase shear at the joints. The next step is to clean and polish the
surface after the base slab has been poured. The next pour is done on top.
The footing is the next component. The base footing is the part of the wall that is embedded in
the soil. This footing is longer than the base footing. This footing serves to increase the wall’s
self-weight. The soil above the footing acts as an extension of the wall and adds weight to the
base of the footing. The restoring period is also enhanced by the heel. The foundation slab size
will affect the height of your base footing.
A cantilever retaining wall is the most common type. It can be built on-site or prefabricated. The
base slab’s toe- and heel portions are attached to the wall slab. It takes less concrete to
construct than a gravity retaining wall. To reduce the bending moments of vertical walls, there
are counterforts. A concrete cantilever foundation can be used to construct a concrete retaining
wall.
The active earth pressure coefficient is a useful tool to calculate the lateral force a wall will feel
from backfill. But, this only works if the wall yields sufficiently. The wall height, section modulus,
as well as the design of backfill, all play a role in the wall’s yielding. If these factors are correct,
then the retaining wall will have the capacity to withstand lateral forces. A wall can hold loads up
to 4 tons per square foot.
The drainage system is the second component of a retention wall. To reduce hydrostatic stress,
the retaining wall must have proper drainage. It must have slope protection to prevent it from
sliding. It could become very unstable if it is not. There are many types of retaining walls. Here’s
how to choose the right one for you. These are the components of a typical retaining wall.
Cantilever-retaining walls are vertical structural elements designed to resist lateral Earth
pressure. The design process involves both structural and geotechnical considerations. The first
step is determining the load bearing capacity of retaining walls. This requires careful
consideration of the risk that walls could tip over or slide, which are two main causes of wall
collapses. In the 1980s, lateral earth pressure theories were developed and were the basis for
the first geotechnical designs of retaining walls.
A cantilever wall retaining wall must be designed to withstand different failure modes.
Stabilization of the structure requires reinforcement at all points. This design illustrates how to
optimize the cantilever wall. It also provides multiple options to optimize a design for each failure
mode. It also provides a model to help you visualize the design process. You can also view
examples of a typical cantilever retaining wall in ASDIP RETAIN.
A pressure relief shelf may also be added to a cantilever retaining wall. Pressure relief shelves
are more economical to build if they are used correctly. A relief shelf can help reduce the
construction cost by up to 15% to 25%. The results from the Staad-Pro analysis are similar to
those of the model study. This type of retaining wall is often used in coastal areas.
