How is the skin friction of bored piles to be entered correctly?


In the example, I have created a model with a 0.5 m wide member.
Assuming a foundation of 200kN / m³, the translational spring corresponds to 200kN / m³ = 100kN / m² * 1 / 0.5m.

If you want to support the member with springs, multiply the foundation with the member width (100kN / m³).

If you now want to additionally consider the skin friction, you have to include the circumference in the calculation (see Solid, for example).
