Basic Data

This part of the window allows us to introduce basic soil parameters - unit weight, angle of internal friction, and cohesion. The particular values are obtained from a geotechnical survey or from laboratory experiments. If this data is not available, it is possible to exploit the built-in soils database, which contains values of selected soils characteristics. The rocks characteristics are not listed in the built-in database, these parameters must be defined manually.

Parameters of the internal friction and cohesion angle are specified as effective or total depending on the settings in the "Stress analysis" combo list. Whether to use effective or total parameters, it depends primarily on the type of soil and load, structure duration, and water conditions.

For effective stress, specify the angle of internal friction between the soil and the structure, which depends on the structure material and type of soil. Possible values of this parameter are listed in the table of recommended values.

For total stress, specify the adhesion of soil to the structure face a.

The associated theory is described in detail in the chapter "Earth pressures".
