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 geotechnical survey or from laboratory experiments. If these data are not available, it is possible to exploit built-in, 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. Approximate parameters of rocks are presented in the theoretical part of the Help .
Soil parameters differ according to the analysis type and analysis method ("" frame, " " and " " tabs).
The analysis type differs according:
- cef, φef are used commonly. effective parameters of shear strength of soil
- cu. Effective angle of internal friction φef is defined only for calculaction of to solve . : depends on undrained shear strength of soil
- φ, σc, D, mi and Geological Strength Index. : for this analysis method program defines
The associated theory is described in detail in chapter "".
