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

Answer

In the example, I have created a model with a 0.5 m wide member.
Assuming a foundation of 200kN/m³, the translational spring constant 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 surface friction, you have to include the scope in the calculation (see Example Solid).
