What is gravity retaining wall?

Gravity retaining walls are the walls which use their own weight to resist the lateral earth pressures. The main forces acting on gravity retaining walls are the vertical forces from the weight of the wall, the lateral earth pressure acting on the back face and the seismic loads.

Which retaining wall is more economical?

Mechanically Stabilized Earth (MSE) Retaining wall
Mechanically Stabilized Earth (MSE) Retaining wall It is among the most economical and most commonly constructed retaining walls.

What is the cantilever retaining wall?

Cantilever retaining walls Cantilever walls are built using reinforced concrete, with an L-shaped, or inverted T-shaped, foundation. The vertical stress behind the wall is transferred onto the foundation, preventing toppling due to lateral earth pressure from the same soil mass.

What is the maximum height for cantilever retaining wall?

Cantilever retaining walls are found best up to a height of 6m. For greater heights earth pressure due to retained fill will be higher due to lever arm effect, higher moments are produced at base, which leads to higher section for stability design as well as structural design.

How deep should posts be for a retaining wall?

Retaining wall posts should be at least as deep as the amount of soil they will be holding. A good rule of thumb is to halve the height of the wall and then add 4 inches. This is how deep you should place your posts.

What is semi gravity retaining wall?

Semi gravity retaining wall is a special form of the gravity retaining wall. In this type of retaining wall, a small amount of steel reinforcement is used near the back face in order to minimize the size of wall section.

What are some examples of gravity retaining walls?

Here below is a few examples of gravity retaining walls. Cantilever retaining walls utilise the weight of the soil to hold down a portion (foundation or pile) and the stiffness of the connection to accomplish a cantilever of the wall. Think of a branch connected to a stem, the branch is a cantilever.

Are counterfort retaining walls more economical than cantilever retaining walls?

Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft. Gravity retaining walls depend on their own weight and any soil resting on the concrete in resisting lateral earth forces.

What are the parts of a cantilever retaining wall?

Cantilever Retaining Walls. Cantilever retaining walls are constructed of reinforced concrete. They consist of a relatively thin stem and a base slab. The base is also divided into two parts, the heel and toe. The heel is the part of the base under the backfill. The toe is the other part of the base.

What are the different types of retaining walls?

Four Common Types of Rigid, Monolithic Concrete Retaining Walls. Cantilever Retaining Walls. Cantilever retaining walls are constructed of reinforced concrete. They consist of a relatively thin stem and a base slab. The base is also divided into two parts, the heel and toe.
