GGU-SLICE: "Soils" menu item
This menu item is only activated for multi-layer systems.
The soil properties input for other systems is carried out in the menu item "Edit/System parameters".
In a multi-layer system the system's soil properties are defined in the following dialog box:
Base of soil layer [m]
Unit weight of moist soil [kN/m³]
Unit weight of buoyant soil
Friction angle
Cohesion c [kN/m²]
Using the "Common soils" button, you can easily select the soil properties of many common soils from a database or determine intermediate values. In the dialog box, which you open by pressing the "Common soils" button, open the "Soils_english.gng_ggu" file when first starting the program in English ("Edit table"/"Load" buttons). Then save the data set in the "Soils.gng_ggu" file on the program level in order to open your modified database file when the program starts. You can also enter your own data ("Edit table"/"x soils to edit" button) and save it in the "Soils.gng_ggu" file. You can also use your adapted file in other GGU programs by means of the "Common soils" function if you copy the file into the appropriate GGU program folder.
If you would like to display a soil structure using either less or more layers, you can define the necessary number of layers using the "Edit no. of soils" button. Click the "Sort" button to sort the soil layers according to depth; however, this is performed automatically when you click "OK" to leave the dialog box. This eliminates the possibility of input errors.
You can also use this function to eliminate a soil from the table.
Simply assign the soil to be eliminated a greater layer depth and then click the "Sort" button. The corresponding soil is now the last soil in the table and can be deleted by reducing the number of soils.
