What it is
A tunnelling method that exploits the geological strength of the surrounding rock and sophisticated monitoring to optimise lining, developed by Rabcewicz, Müller and Pacher and named by Rabcewicz in a lecture.
What it led to
- A revolution in the modern tunnelling industry
- Sequential excavation method (SEM) and sprayed concrete lining (SCL)
- Cost reductions compared with reinforcing the entire tunnel
- Widespread use even in karst geological conditions
