New AZ sheet pile profiles

Sheet piles can be modeled using a step-by-step (phased) analysis. This means that soil, loads, supports, anchors and struts can be added or removed, and the water table changed, for each AZ52-700 stage.Design guidance provided herein is intended to apply to wall/soil systems of traditional heights and configurations in an essentially static loading environment.The free earth support method gives a pressure distribution that would apply when the wall is on the point of failure by rotation about the anchor.A verification report containing all results according to the AZ26-700,AZ28-700 design procedure is also available.

The fixed earth support method is unlikely to represent the true loading at any stage. Both methods tend to over-estimate the bending moment in the pile. The free earth support method is simpler. Several AZ50-700 layers can be defined, divided by horizontal layer boundaries. Soil properties are input for each layer. The bottom AZ400-700N,AZ42-700N is assumed to be infinitely thick.

Where a system is likely to be required to withstand the effects of an earthquake as a part of its design function, the design should follow the processes and conform to the requirements of "A Manual for Seismic Design of Waterfront Retaining Structures" (U.S. Army Engineer Waterways Experiment Station (AZ48-700) in preparation). The surface level on both sides of the pile must be identical and horizontal.

A row of interlocking, vertical pile segments driven to form an essentially straight wall whose plan dimension is sufficiently large that its behavior may be based on a typical unit (usually 1 foot) vertical slice.Externally calculated undisturbed soil displacements can be imposed on the pile. AZ46-700N can also calculate the influence of discrete bending moments and/or horizontal and normal forces on the pile. In the fixed earth support, depth provided is more, moment through out the section reduces, so thiner section is to be provided.Along the pile, several cross-sections with different widths and stiffness can be specified.In the free earth support, depth provided is less, moment through out the section is more than fixed earth support, so thicker section is to be provided.

Two different methods for design calculation according to AZ44-700N and AZ46-700N (NL) are implemented: one using the partial factors prescribed by the design approach in all construction stages (method A) and the second using them only for a selected stage (method B). A sheet pile wall which derives its support solely through interaction with the surrounding soil. A sheet pile wall which derives its support from a combination of AZ26-700 interaction with the surrounding soil and one (or more) mechanical devices which inhibit motion at an isolated point(s). The connection of the AZ42-700N pile to a foundation can be modeled by defining a fixed support or a spring support at a certain level.

A cantilevered sheet pile wall whose primary function is to sustain a difference in water elevation from one side to the other.Comparison between AZ48-700 and AZ50-700 is the same as a cantilevered retaining wall. A AZ44-700N sheet pile wall may be a floodwall in one loading condition and a retaining wall in another.For the support conditions a AZ400-700N distinction is made between translation and rotation. The design procedures described in this manual are limited to a single level of AZ28-700 A special case of a cantilevered wall consisting of sheet piling in the embedded depth and a monolithic concrete wall in the exposed height.The water level determines the hydrostatic water pressure. AZ52-700 can also be introduced, varying linearly across each soil layer.A sheet pile wall (cantilever or anchored) which sustains a difference in soil surface elevation from one side to the other. The change in soil surface elevations may be produced by excavation, dredging, backfilling, or a combination.
