Displacement at max. soil friction [UF]

Calculation of displacement at maximum soil friction

The soil range of importance for the displacement at maximum soil friction is from 200 mm above to 200 mm below the pipeline.

The displacement at maximum soil friction is directly specified by the ultimate friction distance property as can be specified for each soil type (averaged over range from 200 mm above pipeline to 200 below pipeline).

NEN3650-1:2012

In case of an HDD (Horizontal Directional Drilled) pipeline part, the displacement at maximum soil friction is set to 8 mm (and the pipe-soil friction is set to zero).
