GGU-TRENCH: "New" menu item

Click on this menu item to create a new wall system.

You decide whether the necessary verifications are to be performed using the partial safety factors to DIN 4126:2013, or using the global safety factors to the old DIN 4126. In order to guarantee the compatibility of the older records it is still possible to select DIN 4126-100 here. Eurocode 7 with national annex 'DIN 1054:2010' refers to the DIN 4126:2013. For the sake of formality, the expression 'DIN 4126' can be prefixed by 'EC 7' when printing. Just activate the "Add 'EC 7' designation" check box. You can enter a project identification, which will subsequently be entered in the General legend.

Analysis compliant with DIN 4126 5.3 requires the characteristic value of the buoyant unit weight of the soil in the slurry. The buoyant unit weight of the soil may be adopted as an approximation. If the check box "Analysis of slip of individual grains with gam(s) and n" is deactivated, the buoyant unit weight of the soil is adopted for analysis. Otherwise, a more precise analysis compliant with DIN 4126 5.3 is performed.

If you activate the "Use absolute heights" check box, all information with regard to trench depth, guide wall depth, suspension level, groundwater level and depth of soil layers can be given in absolute heights (e.g. in m AD). In the dialog box for diaphragm wall input (see menu item "Edit/Diaphragm wall") the height of the ground level must then also be entered in absolute figures. In all relevant dialog boxes, the input value will be shown as [m AD] instead of [m]. This simply provides clarity. You are, of course, free to select a reference level other than [m AD]. If you do not activate the "Use absolute heights" check box, ground level is assumed to be 0.0 m and all depth information is positive downwards.

Here, you can predefine the unit for the "d10" soil property (see Section "Edit/Soils"). If the check box is not activated, this will be in [m].
