Schieferung
Soils can be introduced with foliation. It means that at a certain angle the soil has significantly different (usually worse) parameters (c a φ). In the program, the angle of foliation inclination and its dispersion are defined, so the modified parameters will be used within +- value of the dispersion from the specified foil inclination. The inclination of the foliation is always entered between 0 and 180°.
If the slope of a slip surface segment or the slope of the interface between blocks is assumed within this range, the analysis proceeds with the modified parameters of cf and φf.
The slope of the foliation can be displayed as a hatching of the soil - e.g. the grey soil in the image below has a defined foliation angle of 150°. The display is switched on in the drawing settings.
