Pile Base Resistance
The bearing capacity of the pile base in cohesionless soils is based on the formula:
where: | σef,b | - | effective stress at the pile base |
Nq | - | ||
αt | - | dimensionless coefficient dependent on pile length and diameter | |
qb | - | pile base resistance | |
qb,lim | - | ||
Ab | - | area of the pile base |
The maximum vertical effective stress at the base of the pile σef,b is limited to 3.2 ksf (approx. 153 kPa).
Bearing capacity factor Nq , coefficient αt ,and limit resistance at the pile base qb,lim are calculated by the program automatically, but it is also possible to input them manually.
