Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied.
Cantilever sheet pile wall design example.
Now we will learn how to analyze and design each type.
Tables 1 and 2 present the soil properties and the stratigraphy respectively.
Segmental retaining walls 17.
Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation.
For this height of sand determine the maximum bending moment in the sheet pile wall.
The figure below presents the project model.

Table 3 presents the external loads.
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.
In such walls the sheet piles are act as a wide cantilever beam above the dredge line.
Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line.
Restrained non yielding walls 20.
Pilaster masonry walls 19.
Wood retaining walls 14.
Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m.
The soil is uniform as shown in the figure.
A sheet pile wall is required to support a 12 excavation.
Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall.
The design of sheet pile walls is a very complex undertaking.

The total length of the sheet pile wall is h d 10 14 6 24 6.
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.
Many engineers use the cantilever wall term to actually describe gravity walls.
Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation.
Cantilevered tilt up walls 13.
To take into account the friction between the wall and the soil we use friction angle δ φ 2.
