Cantilever Retaining Wall Reinforcement Design

The base is divided into two parts the heel and toe.

Cantilever retaining wall reinforcement design.

Geometric design variables were chosen with reference to geometry of the wall and structural design variables were modelled concerning to the critical sections of the wall. Retaining walls example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of 30. Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall. Cantilever retaining wall is the most common type of earth retaining structure.

A gravity wall h 3m masonry or stone b cantilever wall h 3m and h 6m c counterfort wall h 8m d buttress wall transverse stem support provided on front side e e bridge abutment additional horizontal restraint from bridge deck a gravity wall h 3m masonry or stone. Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage. There are eight geometric and four structural design variables for the reinforcement concrete cantilever retaining wall with the shear key as shown in fig. Assuming that the allowable bearing pressure of the soil is 120 knm 2 the.

It is the length from face of the wall stem to rear end of the base slab which includes the thickness of stem. Retaining wall retains earth when level difference exists between two surfaces. It is constructed of reinforced portland cement hellip. Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.

Rw01 concrete masonry reinforced cantilever retaining walls edition e3 may 2013 isbn 0 909407 56 8. These design methods are discussed in detail in allowable stress design of concrete masonry tek 14 7a and strength design of concrete masonry tek 14 4a refs. It is extensively used in variety of situations such as highway engineering railway engineering bridge engineering and irrigation engineering. Recommended stem designs for reinforced cantilever retaining walls with no surcharge are contained in tables 1 and 2 for allowable stress design and strength design respectively.

It has much thinner stem and utilize the weight of the backfill soil to provide most of the resistance to sliding and overturning. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
