Tunnel Standards¶
Use this dialog to define the tunnel's parametric description based on standards.
Where can I find the dialog?¶
In the toolbox, select SFI Model - Tunnel - Parametric Description - Standards.
The standard defines several different tunnel profiles, T4–T14.0. The table below provides geometric dimensions for the various tunnel profiles.
| Profile | Total Width (BT) | Carriageway Width (Bk) | Center Distance Wall Radii (X) | Center Height Wall Radii (Yv) | Wall Radius (Rv) | Center Height Crown Radius (Yh) | Crown Radius (Rh) |
|---|---|---|---|---|---|---|---|
| T4 | 4.0 | 3.0 | - | - | - | 1.330 | 2.400 |
| T5.5 | 5.5 | 3.5 | 3.402 | 1.77 | 4.79 | 3.171 | 2.587 |
| T8.5 | 8.5 | 6.5 | 0.402 | 1.77 | 4.79 | 1.981 | 4.500 |
