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 |
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 is calculated by the program automatically, or it is also possible to input it manually in the "Adding new soils" dialog window.
For cohesive soils, the following formula applies:
where: | α | - | adhesion coefficient in the layer |
cu | - | total cohesion in the layer |
Adhesion coefficient α is calculated by the program automatically, or it is also possible to input it manually in the "Adding new soils" dialog window.
