You can enter the data for the soil massif type Soil Boring Logs in the dialog box below.
Boreholes
In area (1), the boreholes from which the massif is to be generated must be assigned to the massif. This can be done directly by entering the number of the respective sample in the corresponding field or by selecting the graphical selection.
Soil Massif Geometry
In area (2), the soil massif geometry is defined. The topology type describes the shape of the base area of the massif.
Specify the center of the surface of the soil massif. The values a and b describe the total lengths of the outer edges of the massif.
The top edge of the massif results from the top edge of the soil samples. The depth of the massif is described by ΔZ.
It is possible to define a rotation about the z-axis for the massif.
Options
If the groundwater level is to be taken into account in the subsequent analysis of the soil massif, the corresponding check box must be selected under Options in section (3). By activating the check box, the ground water surface is generated from the respective ground water levels of the assigned soil samples and entered in the check box field.
You can also activate the "Settings for layer for layer interfaces" check box here. This creates a tab with the same name next to the Main tab of the soil massif. Here, you can set the support points of the splines that define the layer boundaries.
Both options and their effects are shown in the following figure.
Generate
If the soil massif is completely described by the input values, you can create it by clicking the "OK" or "Apply" buttons.
Using the Generate function, a soil massif consisting of one solids of the "Soil" type per layer is created according to the specified geometry and layering from the soil samples. For this, the boundary surfaces of the soil layers of the solids are approximated by means of surfaces of the type NURBS. If a two-dimensional type is selected as the Type of soil image, the generated solids are deactivated for the calculation, as they are only required for the determination of the elastic constants of the support.
Furthermore, the surface supports of the lateral and bottom boundary surfaces are generated if has been selected as a three-dimensional soil representation. As a support, a hinged surface support is defined on its bottom side and roller supports, which allow displacements parallel to the surface, are selected for the lateral edge surfaces.
The generated support can be found and viewed in the Surface Supports subfolder of the Types for Surfaces folder in the Navigator - Data. This can be seen in the following figure.
