Pile Base Resistance
The bearing capacity of the pile base in drained soils is given by the formula:
where: | σef,b | - | effective stress at the pile base |
Nq | - | bearing capacity factor | |
Nc | - | bearing capacity factor | |
φef | - | angle of internal friction at the pile base | |
cef | - | effective cohesion at the pile base | |
qb | - | pile base resistance | |
Ab | - | area of the pile base |
Bearing capacity factors Nq and Nc are calculated by the program automatically, but it is also possible to input them manually.
For undrained soils it works as follows:
where: | σtot,b | - | total stress at the pile base |
cu | - | total cohesion at the pile base |
