Cantilever sheet pile wall design example.

Segmental retaining walls 17. Wood retaining walls 14. Sheet pile walls. In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation.

Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation. Designing the cantilever wall stem 9. The figure below presents the project model. For this height of sand determine the maximum bending moment in the sheet pile wall.

The total length of the sheet pile wall is h d 10 14 6 24 6. Many engineers use the cantilever wall term to actually describe gravity walls. Swimming pool walls 18. Table 3 presents the external loads.

The soil is uniform as shown in the figure. Pier and pile foundations 11. A sheet pile wall is required to support a 12 excavation. Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation.

Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied. Cantilevered tilt up walls 13. Tables 1 and 2 present the soil properties and the stratigraphy respectively. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

Design of cantilevered wall granular soil. Design of cantilevered wall granular soil. Design of sheet pile walls using truline composite wall sections design methods and examples introduction this report presents the recommended structural capacities for truline composite wall sections and a summary of design methods commonly used to design cantilevered and anchored sheet pile structures. Cantilever sheet pile design.

Counterfort retaining walls 12. For our purposes we will further simplify the process by increasing the entire penetration below the dredge line by 20 thus d 12 2 0 2 12 2 14 6. Restrained non yielding walls 20. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m.

In such walls the sheet piles are act as a wide cantilever beam above the dredge line. Now we will learn how to analyze and design each type. 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. The design of sheet pile walls is a very complex undertaking.

Pilaster masonry walls 19. Cantilever walls cantilever wall design. Civiltech softwareshoring examples 1. 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.
