Cantilever Sheet Pile Wall Design Example

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

Cantilever sheet pile wall design example.

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. In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation. Pilaster masonry walls 19. Several design examples are provided.

Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall. Segmental retaining walls 17. For this height of sand determine the maximum bending moment in the sheet pile wall. Design of cantilevered wall granular soil.

Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line. Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied. A sheet pile wall is required to support a 12 excavation. Now we will learn how to analyze and design each type.

In such walls the sheet piles are act as a wide cantilever beam above the dredge line. Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation. Design of cantilevered wall granular soil. Tables 1 and 2 present the soil properties and the stratigraphy respectively.

Pier and pile foundations 11. Many engineers use the cantilever wall term to actually describe gravity walls. Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00. Sheet pile walls.

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. Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation. Counterfort retaining walls 12. Civiltech softwareshoring examples 1.

The soil is uniform as shown in the figure. The design of sheet pile walls is a very complex undertaking. 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. 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.

Table 3 presents the external loads. Designing the cantilever wall stem 9. Restrained non yielding walls 20. Wood retaining walls 14.

Cantilevered tilt up walls 13. The figure below presents the project model. Swimming pool walls 18. The total length of the sheet pile wall is h d 10 14 6 24 6.
