How to correctly enter the skin friction of bored piles?


In the example I made a model with a 0.5m wide bar.
Assuming a bedding of 200kN / m³, the Wegfeder corresponds to 200kN / m³ = 100kN / m² * 1 / 0.5m.

So if you want to store the rod in a springy way, multiply the bedding by the bar width (100kN / m³).

If you now also want to consider the skin friction, you must include the circumference in the calculation (see example volume).
