Cantilever Sheet Pile Wall Design Example

A sheet pile wall is required to support a 12 excavation.

Cantilever sheet pile wall design example.

Restrained non yielding walls 20. Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line. Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00. Cantilever walls cantilever wall design.

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. 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. To take into account the friction between the wall and the soil we use friction angle δ φ 2. 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.

Many engineers use the cantilever wall term to actually describe gravity walls. Swimming pool walls 18. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m. Counterfort retaining walls 12.

Table 3 presents the external loads. Cantilever sheet pile design. Several design examples are provided. Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall.

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

Now we will learn how to analyze and design each type. Pilaster masonry walls 19. The total length of the sheet pile wall is h d 10 14 6 24 6. The soil is uniform as shown in the figure.

Segmental retaining walls 17. Designing the cantilever wall stem 9. The figure below presents the project model. The design of sheet pile walls is a very complex undertaking.

For this height of sand determine the maximum bending moment in the sheet pile wall. Cantilevered tilt up walls 13. 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. Sheet pile walls.

Pier and pile foundations 11. Design of cantilevered wall granular soil. Tables 1 and 2 present the soil properties and the stratigraphy respectively. Civiltech softwareshoring examples 1.
