What Are the Components of a Retaining Wall?

A good understanding of the components is essential for creating a retaining wall. These components will allow you to create a retaining walls that will last and hold back soil.

Cantilever retaining wall

This design allows for smaller foundations and less concrete than a gravity-retaining wall. Soil parameters are important when designing a cantilever retaining wall besser blocks adelaide. These parameters include the soil’s cohesive strength, density, and elevation difference between the soil’s upper and lower surfaces. This helps determine the amount of pressure the soil can bear under a cantilever.

The lateral earth pressure depends on the direction of the retaining wall, the angle of the internal friction, and the cohesive strength of the soil. It is zero at the top of the wall and increases with depth. This can be a shear key or a bending key.

A typical cantilever retaining wall consists of a toe, and a heel. Depending on the type of wall, the stem can be masonry, or concrete, or even a combination of both. The base is an additional component of cantilever retaining walls.

Soil permeability, or the ability of the soil to retain moisture, can also affect the design of a cantilever retaining wall. If the ground is soft, the wall may fail when the lateral earth pressure is greater than the capacity of the wall. This failure can occur due to the formation of a slip circle.

Relieving platform

Adding a relieving platform to a cantilever retaining wall increases the overall stability of the structure. The relieving platform reduces the lateral earth pressure, thereby reducing the acting maximum bending moment and bending moments of the wall. In addition, the relief platform decreases the lateral pressure on sheeting, and thus makes the wall more stable.

Several researchers have performed tests on the deformation of a retaining wall with a relieving platform. Some of the research findings were based on comparisons of bending moments and rib pillar deformation. In addition, some of the researchers calculated the effect of a relief shelf on the active earth pressure thrust. These research results can be used as a basis for garden designs adelaide principles and calculation methods.

Yakovlev conducted several experiments to determine the pressure distribution over the height of a wall, as a function the platform’s location and intensity. The study also investigated the stress of the backfill behind the wall. He concluded that the internal sliding surface developed from the end of the shelf.

Jumikis, another researcher, looked at the effects of a relief shelf on counterfort walls. Jumikis extended the relief shelf to the theoretical rupture surface. He found that the total deflection increased in the long run. This could be due to relaxation of reinforcements. The researchers also examined the effect of the foundation soil resistance coefficient proportional coefficient on the results. They determined that the effective lower and upper limit values for the unloading board are very high.

Moreover, the researchers investigated the distribution of pressure on the shelf as a function of depth, width and rigidity. The lateral pressure increases linearly when there is less slope than the cantilever. They also measured the Earth pressure at its bottom. They found that the measured value was 1.33 times the Rankine theory’s calculation value. The paper discusses the results.

The lateral earth pressure at the shelf is high. This could lead to a slight decrease in concrete quantities. This could also cause a shift in the center gravity of the failure wedge. In this case, a lateral earth pressure under the shelf might not be beneficial for the retaining wall, but it could cause a small decrease in the reinforcements. The retaining wall is 12 meters high and horizontally wide. To measure horizontal displacement of the retaining walls, the model has ten dial indicators.


Retaining walls are a common way to reduce the slope of a landscape. You can use retaining walls as an independent structure or as part of larger construction projects.

A basic understanding of design principles is essential for designing a retaining wall. The pipe should be able to exit from the wall at least every 50 feet. The amount of reinforcement needed in a retaining wall will vary depending on the type of wall and the total cost of the project. The total amount of steel reinforcement required for a typical retaining walls will depend on how many vertical stems there are, the dimensions of each stem, and the height. Retaining walls designed to carry high loads will have a larger amount of reinforcing than those that carry light loads.

The ACI 318-14 code sizing process aims to reduce the cost and meet the design requirements. The FRFD, or maximum safe factor against sliding, is the sum of horizontal load times the corresponding lever arm. The qmin, or soil pressure intensity under the heel, is another important constraint in retaining wall design. This is because the tensile strength of the soil is weak below the heel. However, it can be difficult to achieve the optimal design.
