Cantilever Sheet Pile Wall Design Example

Table 3 presents the external loads.

Cantilever sheet pile wall design example.

Wood retaining walls 14. Sheet pile walls. To take into account the friction between the wall and the soil we use friction angle δ φ 2. Tables 1 and 2 present the soil properties and the stratigraphy respectively.

In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation. 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. 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. Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation.

Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m. Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall. Restrained non yielding walls 20. 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. Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00. Design of cantilevered wall granular soil.

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. Several design examples are provided. The figure below presents the project model.

Segmental retaining walls 17. 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. Pilaster masonry walls 19.

Civiltech softwareshoring examples 1. Pier and pile foundations 11. Cantilevered tilt up walls 13. Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation.

Designing the cantilever wall stem 9. Now we will learn how to analyze and design each type. For this height of sand determine the maximum bending moment in the sheet pile 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.

The design of sheet pile walls is a very complex undertaking. Many engineers use the cantilever wall term to actually describe gravity walls. In such walls the sheet piles are act as a wide cantilever beam above the dredge line. Cantilever walls cantilever wall design.
