Not Another Teen Movie.The New Austrian Tunneling method (NATM) was developed between
1957 and
1965 in
Austria. It was given its name in
Salzburg in
1962 to distinguish it from old Austrian
tunnelling approach. The main contributors to the development of NATM were Ladislaus von Rabcewicz, Leopold Müller and Franz Pacher. The main idea is to use the geological
stress of the surrounding
rock mass to stabilize the tunnel itself.
