Longitudinal displacement [UF]

Longitudinal displacement [UF]

Specification of longitudinal displacement to develop maximum soil friction specified along pipeline axis (Input Table)

Table description:

Through the input data table UF the longitudinal displacement to develop maximum longitudinal friction along the pipeline axis is provided to the soil model.

The soil parameter is provided as a polygon data line projected on one of the available coordinate axes by means of reference points. The value of the soil parameter is attached to each pipeline node by relating the coordinate of the node to the polygon data line and interpolating the parameter values at the adjacent reference points.

Coordinates of successive data table lines shall have increasing values. The values given for the soil parameter are interpreted as 'mean' values. These values are altered by means of the uncertainty factor UNCF according to the data provided in the input data table UNCER.

In case a stochastic analysis is being made, the UNCF values are interpreted as standard deviations.
