This part of the window serves to introduce basic parameters of soils - unit weight, angle of internal friction, and cohesion. The particular values are obtained from a geotechnical survey or from laboratory experiments. If these data are not available, it is possible to exploit the built-in database of soils, which contains values of selected characteristics of soils. The characteristics of rocks are not listed in the database built, these parameters must be defined manually.
When calculating the cross-section bearing capacity according to Salas, moreover, enters elastic modulus E.
The associated theory is described in detail in the chapter "Micropile".
