They are a blend of the gravity wall and the cantilever wall designs. Can be precast in a factory or formed on site.
The toe is the other part of the base. To support something physically with, or as if with, a prop or buttress.

Gravity retaining walls depend on their own weight and any soil resting on the concrete in resisting lateral earth forces. <. 95 0 obj A secondary effect is to increase the weight of the wall from the added concrete. The heel is the part of the base under the backfill. 1.
A specialized form of gravity walls is a semi-gravity retaining wall.
They are generally economical up to 10 feet in height for cast concrete structures.

They consist of a relatively thin stem and a base slab. Cantilever retaining walls are constructed of reinforced concrete. design of counterfort is explianed step by step with simple procedure of design. %PDF-1.4 These have some tension reinforcing steel included so as to minimize the thickness of the wall without requiring extensive reinforcement. 1- Gravity wall-Masonry or Plain concrete 2- Cantilever retaining wall-RCC (Inverted T and L) 3- Counterfort retaining wall-RCC 4- Buttress wall …
4. Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft. In retaining wall. Some common materials used for retaining walls are treated lumber, concrete block … 4) Buttress wall-RCC.
endobj Creative Commons Attribution/Share-Alike License; (architecture) A brick or stone structure built against another structure to support it. %���� A counterfort retaining wall is a cantilever wall with counterforts, or buttresses, attached to the inside face of the wall to further resist lateral thrust. Use much less concrete than monolithic gravity walls, but require more design and careful construction. Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft. These webs are known as counterforts. As a verb buttress is to support something physically with, or as if with, a prop or buttress. See Wiktionary Terms of Use for details. Buttressed Retaining Walls: When the triangular beams are placed on the front side of the retaining wall, instead of on the backfill side under certain situations, the retaining wall is known as buttressed retaining wall, and the triangular beams are known as buttresses, instead of counterforts. uuid:4f95db2e-be91-424a-9989-8bc5860c6969
3 Earth Pressure (P ) Earth pressure is the pressure exerted by the retaining material on the retaining wall.
DESIGN AND DETAILING OF COUNTERFORT RETAINING WALL When the height of the retaining wall exceeds about 6 m, the thickness of the stem and heel slab works out to be sufficiently large and the design becomes uneconomical. Figure 16.6 shows a buttressed retaining wall. However, retaining walls can also be constructed for aesthetic landscaping purposes. application/pdf The base is also divided into two parts, the heel and toe. Counterfort retaining walls are similar to cantilever walls except they have thin vertical concrete webs at regular intervals along the backside of the wall. This pressure tends to deflect the wall outward.

Can be precast or formed on site.
Retaining walls are usually built to hold back soil mass. Anything that serves to support something; a prop. The counterforts tie the slab and base together, and the purpose of them is to reduce the shear forces and bending moments imposed on the wall by the soil. 4.
