Specification of horizontal soil support pressure along pipeline axis (Input Table)
Through the input data table SOILSUP a horizontal soil support at both sides of a cross-section may be specified. The parameter SOILSUP is defined as a soil pressure.
The value of parameter SOILSUP is attached to each mid-element section by relating the coordinate of that mid-element section to the polygon data line and interpolating the parameter values at adjacent reference points.
Coordinates of successive data table lines shall have increasing values. The parameter is taken as a constant at a given cross-section and not varied in the way the other soil parameters are treated.
The horizontal soil support is assumed to act over angles of 120 degrees symmetrically to the horizontal y-axis of the LOCAL element coordinate system.
