Gravity Retaining Wall Design Example

Although wall heights up to 8 ft 2 44 m for conventional gravity walls and 14 ft 4 28 m for soil reinforced walls are presented properly engineered walls can exceed these heights.

Gravity retaining wall design example.

Swimming pool walls 18. Design of slopped gravity retaining wall in excel design of vertical gravity retaining wall sloped type. Soldier pile walls 22. 1 should be consulted.

Sheet pile walls 21. Gravity retaining walls are earth retaining structures that depend primarily on their own self weight and that of any enclosed material to support the retained ground and any structures or loads placed upon it. Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. The wedge is defined as the soil which extends beyond the failure.

Every retaining wall supports a wedge of soil. Cantilever retaining wall reinforced concrete wall with small dimensions and it is the most economical type and the most common note. Example 01 using plum concrete 1 3 6 sloped retaining wall. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.

Restrained non yielding walls 20. 6 foot 1 8 m high gravity retaining wall equivalent fluid pressure of soil 40 pcf 7 1 kn m soil weight 100 pcf 15 7 kn. Wood retaining walls 14. Segmental retaining walls 17.

Setback sliding wedge. Walls formed from interlocking concrete blocks are designed as gravity walls defined in bs 8002 2015 as follows. How retaining walls fail. For a detailed discussion of design and analysis parameters the design manual for segmental retaining walls ref.

Flexural and shear stresses are checked in the second design example and it is seen that the magnitudes are very low. Semi gravity retaining wall reduce the dimensions of the gravity retaining wall by using some reinforcement. Structural design of cantilever retaining wall is depend on separating each. In this example the structural design of the three retaining wall components is performed by hand.

Two equations are developed. Construction topics and caveats 24. A retaining wall that relies solely on it s own weight to stand up is called a gravity wall allan block combines the basic engineering principles of setback leverage and total unit mass with simple mechanics to make highly stable gravity walls. Cantilevered tilt up walls 13.

F c 3000 psi fy 60 ksi natural soil development of structural design equations. Pilaster masonry walls 19. 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.
