End Support: Add / Edit Shotcrete Layer

Shotcrete can be added to the ends of the excavation with the Add / Edit Shotcrete Layer option (End Support view).

Note: it is assumed that the shotcrete covers the entire surface area of the excavation ends. Therefore, it is not necessary to define where the shotcrete is to be applied. The shotcrete will automatically cover the entire exposed face of the end wedges, regardless of the size or position of the end wedges.

Because the shotcrete location does not have to be defined, the application of shotcrete to the ends is simplified - adding or removal of layers is all accomplished with one dialog, as described below.

To add / remove shotcrete on the excavation ends:

  1. First, make sure you are viewing the End Support Design view. Select the End Support Design View button from the toolbar.

  2. Select the Add / Edit Shotcrete Layer option from the Sidebar or the Support menu.

  3. You will see the Add / Edit Shotcrete Layers (on Ends) dialog. A list of all currently defined shotcrete property types will appear at the left of the dialog. (Note: shotcrete properties are created and defined with the Shotcrete Properties option). If shotcrete layers have been applied, the applied layers are listed at the right of the dialog.

  4. To add shotcrete layers:

  5. To remove existing shotcrete layers:

  1. Select OK when you have finished adding / removing layers, and the layers will be applied to the ends of the excavation.

Ordering of Layers

If you have multiple shotcrete layers, the ordering of the layers in the Add / Edit Shotcrete Layers dialog, does not matter. The layers can be applied in any order, and this will not affect the results of the Unwedge analysis in any way.

Display of Shotcrete on Ends

On the End Support Design View, applied shotcrete layers are not displayed directly on the Opening Section (because it would be impossible to represent the display of multiple layers). Instead, applied shotcrete on the excavation ends, is represented by a Legend, which indicates the applied shotcrete layers (name and colour). The Legend appears in the lower right corner of the End Support Design View. Note: the display of a border around this legend can be toggled on or off in the Display Options dialog.
