Pile calculates the vertical load carrying capacities of a range of individual piles in a layered soil deposit. The theory is based on both conventional and new methods for drained (frictional) and undrained (cohesive) soils.

The main features of Pile are summarised below:

• The soil is specified in layers. Each layer is set to be drained(frictional) or undrained(cohesive) and appropriate strength parameters are specified. Maximum values can be set for ultimate soil/shaft friction stress and end bearing stress within each layer.
• The user has four choices for selecting datum - Depth below ground level, depth below mud-line, elevation above Ordnance Datum, and finally a user-specified datum.
• Porewater pressures within the soil deposit can be set to hydrostatic or piezometric.
• The user has the option to calculate the pile capacity for a range of pile depths, for different cross-section shapes such circular, square and H-section. The circular and square cross-sections may be hollow or solid, where as the H-section is only solid. In addition, under-reams or enlarged bases may be specified.
• There are two approaches available to calculate the capacity of the pile - Working load approach and Limit-state approach.
• The graphical output depicts the variation of different pile capacities such as shaft resistance, end bearing, total bearing capacity of the pile etc. with pile depth. This may be exported in WMF format.
• The text output contains the tabular representation of the above data together with the input data. The user also has the option of exporting these results in CSV format.
