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 the selected characteristics of soils. The characteristics of rocks are not listed in the database built, these parameters must be defined manually.
The calculation of "Pile Group" differs according to the type of subsoil:
- cohesionless soil: effective parameters of shear strength of soil cef, φef are used commonly.
- cohesive soil: in program is defined only the value of total shear strength of soil cu, which determines vertical bearing capacity of pile group (or earth block).
The associated theory is described in detail in the chapter "Pile Group".
