Cantilever retaining wall is the most common type used as retaining walls. Cantilever retaining wall is either constructed on site or prefabricated offsite i.e. precast. The portion of the base slab beneath backfill material is termed as heel, and the other part is called toe. Cantilever retaining wall is economical up to height of 10m.
CANTILEVER WALLS Cantilever theory was introduced by Galileo in the 16th Century, then advanced by Sir John Fowler and Sir Benjamin Baker in the 19th Century Reinforced concrete retaining walls were introduced by the
A cantilever retaining wall uses the counter-moment produced by the toe of the wall which must be sunk into the ground at a depth suitable to resist the opposing earth pressure. For example, a steel sheet-pile retaining wall must be fixed below ground at a depth of approximately 2/3s of its overall depth. 5m above ground, 10m below ground.

Precast Concrete Crib Wall . Figure 5.2-1 Typical Gravity Retaining Walls . Semi-gravity cantilever, counterfort and buttress walls are constructed of reinforced concrete. They can be used in both cut and fill applications. They have relatively narrow base widths. They can be supported by both shallow and deep foundations. The position of the wall
A basement wall is thus one kind of retaining wall. But the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
2 - Cantilever Retaining Walls. Cantilever walls are single-layered walls built in uniform thickness with its base connected to a slab. These walls are capable of holding significant amount of earth and can support tall slopes. The structure of the wall determines its strength and its capability to hold a significant amount of earth.
Cantilever Retaining Wall. In this section we will take a simple cantilever retaining wall and discuss the concept of how they are affected by the loads and how you have to design them to resist these loads that they are subjected to. What is a cantilever retaining wall? It is a wall that acts like a cantilever fixed at the bottom foundation.
In cantilever retaining walls, the concrete base or footing holds the vertical masonry wall in position and resists overturning and sliding caused by lateral soil loading. The reinforcement is placed vertically in the cores of the masonry units to resist the tensile stresses developed by the lateral earth pressure.
So I've recently started designing a conventional cantilever retaining wall while working through the preliminary calcs, I became aware of the K active and K passive coefficients that I'm using. I mean, I've always been taught to use these coefficients to calculate the earth pressures acting on the wall.
