They consist of a relatively thin stem and a base slab.
Reinforced concrete gravity retaining wall.
Reinforced concrete retaining wall type 1 and 1sw concrete cantilever wall with flat backfill and flat front face in western wa.
Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.
The base is also divided into two parts the heel and toe.
Refer to figure a 4 for the mass or weight calculations.
Concrete cantilever retaining wall.
Cantilever retaining walls are constructed of reinforced concrete.
It s not dependent on tie black or grid systems for wall stabilization.
It s a gravity type wall that uses the mass of the concrete materials compacted within cells for structural stability.
The reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.
Earthquake seismic design 7.
Designing the cantilever wall stem 9.
The base is divided into two parts the heel and toe.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
The toe is the other part of the base.
Thus it is also called gravity retaining wall.
The heel is the part of the base under the backfill.
In case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight.
There are two checks to consider the stability of the retaining wall.
A semi gravity retaining walls additional loading case in the case of semi gravity concrete retaining walls such as standard plan type 1 there is an additional loading case considered.
Counterfort retaining walls 12.
Wood retaining walls 14.
One is the check for an overturning moment and the other one is the check for sliding.
Gabion walls 16.
This greatly minimizes excavation and back filling required by other retaining wall systems.
Reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line.
Along with load case 1 horizontal backfill and load case 2 sloped backfill of 2 horizontal to 1 vertical and limited to a vertical.
Cantilevered tilt up walls 13.
Retaining wall can be built with masonry along with reinforced concrete.
Building codes and retaining walls 5.
Forces on retaining walls 6.
The heel is the part of the base under the backfill.
Reinforced retaining walls reinforced concrete and reinforced masonry walls on spread foundations are gravity structures in which the stability against overturning is provided by the weight of the wall and reinforcement bars in the wall.
Soil bearing and stability 8.
Criblock is a reinforced concrete retaining wall system.
Use much less concrete than monolithic gravity walls but require more design and careful construction.
Designed for effective peak ground acceleration of 0 51g d 10 15 reinforced concrete retaining wall type 2 and 2sw concrete cantilever wall with flat backfill and sloping front face in western wa.
Pier and pile foundations 11.
