This type is the most effective type when there are limitations in the space. They are generally reinforced concrete structures. Cantilever Retaining Wall Propped Retaining WallĬantilever-type walls are the most common type of structure we observed in the construction. When there are larger forces applied and limitations in increasing the with of the retaining wall, reinforcement is provided with modified based to maintain the stability. However, in semi gravity structure, we provide a certain amount of reinforcement to carry the developed tensile stresses in the surface where the soil pressure is applied. In a gravity structure, generally, we do not provide rebar to carry the load. This is a further development of gravity structures. The gravity retaining structures are mostly observed in the construction of hydraulic structures. However, in some situations, nominal reinforcement is provided as a measure to avid the thermal cracks. In general, gravity retaining structures are constructed as mass concrete structures. However, with the development of the construction industry and after starting using concrete, concrete gravity retaining walls have become more popular. Masonry and stone were used for construction early days.
There are different materials used for the construction of retaining structures.
In other words, the self-weight of the structure act as the counterweight to bear the applied overturning moment. Gravity Retaining WallĪs the name implies, the structure bears the load by the gravity load. It depends on the structural behavior and forces acting on a retaining wall.
The design of retaining structures is not same for the all types of structures. There are other types of retaining structures that retain materials like rock, sand, etc.
Why do we need a Retaining Wall?Īny structure that is used to retain the earth is generally called a retaining wall. Different classifications of retaining systems are also discussed. Retaining wall types and their behavior is discussed in this article.
