Cantilever Sheet Pile Wall Design Example

Cantilever soldier pile design requires that we determine the soldier pile embedment size and estimate lateral wall displacements.

Cantilever sheet pile wall design example.

A sheet pile wall is required to support a 12 excavation. Design the sheet pile and the ground achors with allowable stress methodology and obtain a wall embedment safety factor of 1 5. In this example we will design a cantilever sheet pile wall supporting a 10 ft excavation. Sand 30 d 3 1 75t m sat 1 75t m3 3 00 g w t 1 00.

Designing the cantilever wall stem 9. Table 3 presents the external loads. Wood retaining walls 14. Sheet pile walls.

The figure below presents the project model. Table 4 presents the wall properties. Cantilever soldier pile design. Civiltech software shoring examples 1 example 1 design of cantilevered wall granular soil introduction.

In such walls the sheet piles are act as a wide cantilever beam above the dredge line. Pilaster masonry walls 19. Include 600 psf traffic surcharge 1ft behind the wall for a length of 20ft. Example 1 design the cantilever sheet pile wall that satisfy the requirements for stability of the wall.

Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied. Now we will learn how to analyze and design each type. The soil is uniform as shown in the figure. Segmental retaining walls 17.

Swimming pool walls 18. For this height of sand determine the maximum bending moment in the sheet pile wall. Restrained non yielding walls 20. Cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line.

Several design examples are provided to illustrate the application of these design methods for sheet pile walls using the truline 800 series. Cantilever soldier piles are feasible only if we do not encounter any groundwater above the final excavation subgrade. Tables 1 and 2 present the soil properties and the stratigraphy respectively. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

The total length of the sheet pile wall is h d 10 14 6 24 6. Pier and pile foundations 11. Reinforced piles spaced at 6ft off center while pile diameter is 2 5ft. An excel spreadsheet calculator for the depth of embedment of cantilevered sheet pile walls in sand excel spreadsheet xls xlsx cantilever sheet pile wall cantilevered sand calculator download civil engineering sheetsfree free download 2017 civil engineering courses articles.

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.
