Specification of maximum bearing capacity of sub-soil along pipeline axis (Input Table)

Table description:

Through the input data table RVS the maximum bearing capacity of the sub-soil 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.

The variation parameter VARAR defines a 'band' around the soil parameter value as it is going to be used in calculations, in order to allow for iteration inaccuracy required by the computation model taking into account the non-linear character of the soil model.

Warning The presence of soil is governed by the specification of the RVS, meaning for those parts of the pipeline where the RVS = 0 all other soil parameters will be treated as being zero as well, regardless of any value in the other tables concerned (see M320/1).
