GGU-CANTILEVER: "Soils" menu item

You can define the soil properties in the following dialog box:

If you would like to edit the number of soils, select the "Edit number of soils" or "x soils to edit" button and then enter the new number of soils. Using the "Sort" button, you can have the soils sorted according to depth. This sorting will be carried out automatically when leaving the dialog box, without the function being explicitly called-up. Erroneous input is thus impossible from the outset.

If several soils have been entered, and you would like to delete a soil which is not at the end of the list, you can assign this soil a large depth (e.g. 99.0). Then select the "Sort" button. The soil will now be at the end of the table and can be deleted by reducing the number of soils.

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 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.

All project data can be entered and managed in the GGU-CONNECT program. If you have already stored your drilling data as a soil strata model in your project, you can load the soil strata and properties as an xml file using the "GGU-CONNECT" button in the above dialog box. A brief overview of the procedure in GGU-CONNECT for exporting the data to the GGU analysis programs can be found here:

Layer depths are always with reference to the top of the wall, or are absolute heights (m AD), if this was selected in the initial dialog box of the "File/New" menu item.

If you have activated the "Differentiate active + passive soil properties" check box in the dialog box under "File/New" or "Editor 1/Analysis options", you can enter different weights and friction angles for the active and passive sides.

It is only necessary to enter permeabilities if hydrostatic pressures must be considered, and any hydraulic gradients, using flow conduits (see “Theoretical principles: Water pressure - Approach using flow conduits”).
