The sheet pile can be modeled using progressive (phased) analysis. This means that soil, loads, supports, anchors and pillars can be added or removed for each AZ52-700 stage, and groundwater levels can be changed. The design guidelines provided here are intended to be applied to traditional height and configuration wall / Earth systems sheet pile manufacturers. The free earth support method provides a pressure distribution that is applicable when the wall rotates around the anchor and is at the point of failure. Validation reports that contain all the results of AZ26-700 and AZ28-700 are also available.
Fixed earth support methods are unlikely to represent any stage of real load. The two methods tend to overestimate the bending moments in piles. The free earth support method is simpler. Several AZ50-700 layers can be defined, divided by the horizontal layer boundary. Each layer inputs soil properties. At the bottom of AZ400-700N, AZ42-700N is assumed to be infinitely thick.
If the system may need to withstand seismic effects as part of its design function, the design should follow the procedures and meet the requirements of the "Seashore Retaining Structures Seismic Design Manual" (US Army Engineer). Channel experiment station (AZ48-700) in preparation. The surface height of both sides of the pile must be the same and level.
A row of interlocking vertical piles is driven to form essentially straight walls that are large enough to behave based on a typical unit (usually one foot) vertical slice. The undisturbed soil displacement calculated externally can be applied to piles. AZ46-700N can also calculate the influence of discrete moments and / or horizontal and normal forces on piles. In fixed soil support, the greater the depth provided, the smaller the moment of cross-section, so it is necessary to provide a thinner cross-section. On piles, multiple sections with different widths and stiffness can be specified. In the free soil support, the depth provides less than the fixed earth support, so the thicker part should be provided.
Two different methods of design calculation based on AZ44-700N and A Z46-700N (NL) are: using some of the factors specified in the design method at all construction stages (method A), and using them only at selected stages (method B). Sheet pile walls are supported only by interaction with surrounding soil. Sheet pile walls are supported by a combination of AZ26-700 interaction with surrounding soil and a (or more) mechanical device that inhibits movement at one or more isolated points. The connection between AZ42-700N pile and foundation can be modeled by defining fixed support or spring support at a certain level.
