Counterforts are firmly attached to the face slab as well as the base slab. The earth pressure acting on the face slab is transferred to the counterfort which deflects as vertical cantilever. The back of rear counterfort comes under tension and the front face is under compression. So the inclined (back) face of the rear counterfort should be provided with main reinforcement.

Rear Counterfort Retaining Wall and its Main Reinforcement

A rear counterfort retaining wall is a type of reinforced concrete wall used to retain soil. It consists of a vertical wall, a horizontal base slab, and a series of counterforts, which are perpendicular to the wall and base slab.

The main reinforcement in a rear counterfort retaining wall is provided on the inclined face in the back counterfort. This is because the back counterfort is subjected to tensile stresses due to the soil pressure on the wall. The main reinforcement in the inclined face of the back counterfort helps to resist these tensile stresses and prevent cracking.

Other reinforcement in the rear counterfort retaining wall includes:

- Vertical reinforcement in the wall: This is provided to resist the lateral earth pressure and to ensure the stability of the wall.
- Horizontal reinforcement in the base slab: This is provided to resist the bending moment due to the soil pressure on the wall.
- Reinforcement in the counterforts: This is provided to ensure the stability of the counterforts and to resist the bending moment due to the soil pressure on the wall.

Advantages of Rear Counterfort Retaining Wall

- It is a cost-effective solution for retaining soil.
- It provides excellent stability against the lateral earth pressure.
- It is easy to construct and maintain.
- It allows for a variety of finishes to be applied to the wall surface.

Conclusion

In conclusion, the main reinforcement in a rear counterfort retaining wall is provided on the inclined face in the back counterfort. This reinforcement helps to resist the tensile stresses due to the soil pressure on the wall. Other reinforcement is also provided in the wall, base slab, and counterforts to ensure the stability of the structure. The rear counterfort retaining wall is a cost-effective and stable solution for retaining soil.
