Tunnel Section Library
Depending on the tunnel construction stage, tunnel sections can be roughly divided into the excavation, primary
support, and second lining. The overall steps of tunnel over-excavation using ST-Surv software are
①
enter
[Tunnel Section Library] to design the tunnel section (excavation, primary support, second lining); ② enter
[Feature Point] to add tunnel feature points when needed; ③ enter [Tunnel Over-under Break] to select tunnel
section or feature points for over-excavation operation.
Tunnels on ST-Surv are based on roads, i.e. road design is required before designing the tunnel cross-section.
The steps to set up the tunnel cross-section library are as follows.
1. Pre-requisite: have been in the [Road] - [Road Design] module to design a road (including at least the flat
section).
2. Enter [Tunnel Section Library] and select the designed road at the top bar.

3. After selecting the road, select the type of section to be designed (excavation, primary support, second lining),
and click the "+" hover button at the bottom right corner to enter the tunnel section design interface.
