Cantilever Sheet Pile Retaining Wall

The theory behind the design including soil structure interaction and three dimensional considerations is so complex that an exact design is not even attempted when designing sheet pile walls by hand.

Cantilever sheet pile retaining wall.

It is based on the blum theory a limit equilibrium method lem. 16 figure 8 earth pressure distributions used in design of anchored sheet piling by free. Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation. Use factor of safety 1.

13 figure 7 earth pressures for cantilever sheet pile wall in cohesive soil. Designing the cantilever wall stem 9. A wall for holding in place a mass of earth or the like as at the edge of a terrace or excavation. Free cantilever sheet piles.

Pier and pile foundations 11. There are two types of sheet pile. Wood retaining walls 14. Cantilevered tilt up walls 13.

A sheet pile wall cantilever or anchored which sustains a difference in soil surface elevation from one side to the other. It a sheet pile subject to a concentrated horizontal load at its top. The change in soil surface elevations may be produced by excavation dredging backfilling or a combination. The design of sheet pile walls is a very complex undertaking.

A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. Prosheet is a comprehensive sheet pile design software for cantilever and single supported retaining walls one anchor or strut. Counterfort retaining walls 12. Restrained non yielding walls 20.

It is a quite simple tool to determine all the forces required for designing a sheet pile retaining wall and ideal for preliminary designs. Figure 6 example problem for sheet pile wall in cohesionless soil. Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation. The various forces acting on a cantilever sheet pile wall are the active earth pressure on the back of the wall and the passive earth pressure on the front of the wall.

Above the dredge level there is no backfill. A basement wall is thus one kind of retaining wall. Segmental retaining walls 17. Many engineers use the cantilever wall term to actually describe gravity walls.

Swimming pool walls 18. Cantilever sheet pile design. The free cantilever sheet pile obtains its stability wholly form the larger passive resistance of the soil below the dredge level into which. A sheet pile wall is required to support a 12 excavation.

Please note this value is applied only for passive pressure. Pilaster masonry walls 19. The soil is uniform as shown in the figure. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

A cantilevered sheet pile wall whose. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m.
