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 .
Either effective or total parameters of the angle of internal friction and cohesion are specified depending on the setting in the "Stress analysis" combo list. Whether to usedepends primarily on the type of soil, type of load, structure duration and water conditions.
It may be required to specify the, which depends on the structure material and the type of soil. Possible values of this parameter are listed in the .
The associated theory is described in detail in chapter "".
