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 .
The associated theory is described in detail in chapter "".
For calculation of αs. For coarse-grained soils - sands and gravels further needs to specify the magnitude of and type of grains.according to the , and further needs to specify
