ABSTRACT. A new commuter train tunnel under Stockholm City, is currently
being designed. The main portion of the tunnel is planned to be constructed as
an unlined rock tunnel. The standard rock reinforcement is intended to provide
the stability for all non-critical sections of the tunnel. The rock mass was divided
into four ...

New Austrian tunnelling method - Wikipedia
The New Austrian tunneling method (NATM), also known as sequential
excavation method (SEM), is a method of modern tunnel design and construction.
This technique first gained attention in the 1960s based on the work of Ladislaus
von Rabcewicz, Leopold Müller, and Franz Pacher between 1957 and 1965 in
