where:

σefb

-

effective stress on the pile base

Nq

-

bearing capacity factor

Ab

-

area of pile base

The bearing capacity factor Nq is back-calculated by the program; however, its values can be manually modified.

For cohesive soils, the following expression holds:

where:

cu

-

undrained shear strength at the base
