Cantilever sheet pile walls depend for their support on the.

Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation. User editable customer soil sheet pile soldier pile lagging and frame databases. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m. They make plates of concrete timber and.

The rigid gravity walls develop their soil retaining capacity from their dead weights. Sheet piles walls types and forces of acting on the bulkhead uses. Cantilever walls with attached traffic barriers soil nail walls soldier pile walls soldier pile tieback walls and all walls beyond the scope of the designs tabulated in the standard plans are designed by the bridge and structures office according to the design parameters provided by the geotechnical engineer. Many engineers use the cantilever wall term to actually describe gravity walls.

The semi gravity walls such as cast in place concrete cantilever walls develop resistance to overturning and sliding from self weight and weight of soil above the wall footing. Sheet piles are generally thin piles. A sheet pile wall is required to support a 12 excavation. They are coming to some forces acting on sheet pile walls.

Because cantilever walls derive their support solely from the foundation soils they may be installed in relatively close proximity but not less than 1 5 times the overall length of the piling to existing structures. Use factor of safety 1 5 for. 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. To take into account the friction between the wall and the soil we use friction angle δ φ 2.
