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 the built-in, 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. Approximate parameters of rocks are presented in the theoretical part of the help .
The calculation of "" differs according to the type of subsoil:
- cef, φef are used commonly. : effective parameters of shear strength of soil
- cu, which determines vertical bearing capacity of pile group (or earth block). : in program is defined only the value of total shear strength of soil
Additional parameters are input depending on the settings in the frame "" and in the " " tab.
The associated theory is described in detail in chapter "".
