Cantilever Sheet Pile Wall Design Example

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 sheet pile wall design example.

Design of cantilevered wall granular soil. For this height of sand determine the maximum bending moment in the sheet pile wall. Designing the cantilever wall stem 9. Segmental retaining walls 17.

Sheet pile walls. Now we will learn how to analyze and design each type. 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. Pilaster masonry walls 19.

Swimming pool walls 18. The figure below presents the project model. The soil is uniform as shown in the figure. Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line.

Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall. Several design examples are provided. Cantilever sheet pile design. Wood retaining walls 14.

Cantilevered tilt up walls 13. The design of sheet pile walls is a very complex undertaking. A sheet pile wall is required to support a 12 excavation. Restrained non yielding walls 20.

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. Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00. In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation. Design of cantilevered wall granular soil.

Cantilever walls cantilever wall design. In such walls the sheet piles are act as a wide cantilever beam above the dredge line. Tables 1 and 2 present the soil properties and the stratigraphy respectively. Counterfort retaining walls 12.

Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation. 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. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m. Many engineers use the cantilever wall term to actually describe gravity walls.

The total length of the sheet pile wall is h d 10 14 6 24 6. Civiltech softwareshoring examples 1. Table 3 presents the external loads. Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation.
