They do this by modelling the sheet piles as either a cantilever beam for the embedded sheet pile wall design or as a propped cantilever for the anchored sheet pile wall design.
Cantilever sheet pile wall design spreadsheet.
Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied.
This spreadsheet designs cantilever sheet pile walls anchored sheet pile walls can be designed using the civilweb anchored sheet pile wall design spreadsheet.
It is based on the blum theory a limit equilibrium method lem.
These two spreadsheets can be purchased together as the civilweb sheet pile wall design spreadsheet suite for only 25 a saving of more than 35.
Use factor of safety 1.
Please note this value is applied only for passive pressure.
Design of cantilevered wall granular soil introduction.
Several design examples are provided to illustrate the application of these design methods for sheet pile walls using the truline 800 series.
It is a quite simple tool to determine all the forces required for designing a sheet pile retaining wall and ideal for preliminary designs.
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.
To take into account the friction between the wall and the soil we use friction angle δ φ 2.
A sheet pile wall is required to support a 12 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 soil is uniform as shown in the figure.
