Cantilever Sheet Pile Wall Design Example

Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation.

Cantilever sheet pile wall design example. Cantilever sheet pile design. Pier and pile foundations 11. Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied. Counterfort retaining walls 12.

Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00. 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 sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m. Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line.

In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation. Designing the cantilever wall stem 9. The total length of the sheet pile wall is h d 10 14 6 24 6. For this height of sand determine the maximum bending moment in the sheet pile wall.

Many engineers use the cantilever wall term to actually describe gravity walls. 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. Civiltech softwareshoring examples 1. Segmental retaining walls 17.

Wood retaining walls 14. 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. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

Cantilevered tilt up walls 13. 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. Design of cantilevered wall granular soil.

Swimming pool walls 18. The design of sheet pile walls is a very complex undertaking. Design of cantilevered wall granular soil. Restrained non yielding walls 20.

A sheet pile wall is required to support a 12 excavation. Sheet pile walls. Pilaster masonry walls 19. Several design examples are provided.

The figure below presents the project model. Table 3 presents the external loads. Tables 1 and 2 present the soil properties and the stratigraphy respectively. Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall.
