Pile Shaft Resistance

The bearing capacity of the pile shaft in cohesionless soils is given by the formula:

where:

K

-

coefficient of lateral earth pressure in the layer

CF

-

correction factor

σef

-

effective stress at the middle of the layer

δ

-

pile skin friction angle (between pile material and surrounding soil)

fs,i

-

shaft resistance in the ith layer

As,i

-

area of the pile shaft in the ith layer

Coefficient of lateral earth pressure K, correction factor CF, and pile skin friction angle δ are calculated by the program automatically, or it is also possible to input them manually in the "Adding new soils" dialog window.
