The following worked example is for a free standing cantilever wall that is considered.
Consider the cantilever retaining wall with the cross section shown in the above figure a 1 which retains a 2m depth of soil having the groundwater table at 1 0m level.

The following worked examples have been prepared to illustrate the application of bs8002 to retaining wall design.
In this example the structural design of the three retaining wall components is performed by hand.

Bs8002 introduces radical changes in the design of retaining walls.
Usually the cantilever wall stem is of concrete block construction rising from an in situ concrete foundation.
