Cross sections - TNL5

8.3 Cross-Sections

This option allows one to set out individual points of the profiles within the range between the initial and final station.

The following data is requested:

Cross-section Points: Allows user to set the theoretical points of the tunnel template (see Features and Functionality > Theoretical Points of the Tunnel Template).

Initial Station

Final Station

Station Interval: Station increment value.

Thickness: Allows one to create tunnel templates that are parallel to the theoretical tunnel template. A positive thickness will create a tunnel template with a larger radius and a negative thickness will create one with a smaller radius.

Maximum Difference: Filter which serves to discard points having a displacement perpendicular to the cross-section that is greater than the value indicated.

Initially, the setting out screen shows a graphic with the theoretical points that have been set up. For each profile, these points are set out from left to right. For starting the setting out, the button Start must be clicked on. After finishing the setting out, Cont. button will be enabled for going to next point. The process can be cancelled clicking on Finish button.

For each measurement the program shows the project station of the profile (P StP), the measured station of the profile (M StP) and the difference (Dif) regarding with tunnel template.

After finishing the setting out of the point, it will be drawn in blue color if it meets the tolerances and it has been stored in result file, otherwise it will be drawn in red

Before starting the setting out, several parameters can be modified within the setting option, such as Station tolerances and the number of Iterations.
