Cantilever Sheet Pile Wall Analysis

The objective in analysis of sheet pile walls is to get to a depth of embedment d sufficient for the wall stability.

Cantilever sheet pile wall analysis.

In a limit equilibrium analysis this type of wall is supported by a lateral earth pressure equal to the difference between the active and passive earth pressures above and below a point of rotation. In this example we will design a cantilever sheet pile wall supporting a 3 5 excavation. Spreadsheet calculated total active passive demands on a sheet pile wall considers anchored and cantilevered walls. Cantilever sheet pile walls tend to be prone to movement and are generally only used for temporary structures or for permanent walls of low height in sands and gravels.

Ultimate output required sheet pile embedment depth. Tables 4 and 5 present the wall and support properties respectively. A cantilever sheet pile wall consists of sheet piling driven deep enough into the ground to become a fixed vertical cantilever. The model and analysis have been designed with deepex shoring design software.

The figure below presents the project model. For this purpose one needs to know the lateral earth pressure theory first. Tables 1 and 2 present the soil properties and the stratigraphy respectively. Figure 1 after craig figure 6 22 additional design requirements in addition to the above there are also two other important criteria that are adopted in practical design of.
