Cantilever Sheet Pile Wall Design

Cantilever sheet pile design.

Cantilever sheet pile wall design.

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. A sheet pile wall is required to support a 12 excavation. To take into account the friction between the wall and the soil we use friction angle δ φ 2.

Please note this value is applied only for passive pressure. 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. Design of cantilevered wall granular soil introduction. Sheet pile design by pile buck and the online help for spw 911 explain how that is properly applied.

A cantilevered sheet pile wall performs somewhat like a cantilevered beam. 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. The soil is uniform as shown in the figure.

Several design examples are provided to illustrate the application of these design methods for sheet pile walls using the truline 800 series. Cantilever walls restrain retained earth by the passive resistance provided by the soil below the excavation. The design of sheet pile walls is a very complex undertaking. Use factor of safety 1.

It is a quite simple tool to determine all the forces required for designing a sheet pile retaining wall and ideal for preliminary designs. Design the cantilever sheet pile wall that satisfy the requirements for stability of the wall. The sheet piling is driven to a sufficient depth into the ground to become fixed as a vertical can tilever resisting a load from active earth pressure. Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4 5 m.

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 walls cantilever wall design. 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. Prosheet is a comprehensive sheet pile design software for cantilever and single supported retaining walls one anchor or strut.

It is based on the blum theory a limit equilibrium method lem.
