The new Austrian tunneling method (NATM), also known as the sequential excavation method (SEM) or sprayed concrete lining method [1] (SCL), is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses.
The tunnel significantly enhances connectivity within the Kashmir Valley and is a key component of India's efforts to improve transportation infrastructure in the region. The tunnel was constructed using the New Austrian Tunneling Method (NATM) and was built by Afcons Infrastructure. It features modern safety systems, including escape tunnels ...
The tunnel itself takes up about 82% of the total new line. The Yulhyeon Tunnel was built using the New Austrian tunnelling method (NATM) and is designed for a maximum speed of 300 km/h (186 mph). The average cruising speed is about 240 km/h (149 mph) due to the intermediate stop at Dongtan Station in the southern part of the tunnel. [1]
Franz Pacher (28 April 1919 in Prostřední Suchá, present-day Czech Republic – 3 March 2018 in Salzburg, Austria [1]) was an Austrian civil engineer and a pioneer of modern tunneling. He is one of three men who are considered to be the chief developers of the new Austrian tunneling method (NATM). [2]
The original system as developed by Lauffer is nowadays by many regarded as obsolete but his ideas are incorporated in modern rock mechanics science, such as the relation between the span of a tunnel and the stand-up time, and notably in the New Austrian Tunnelling Method. Reference: Lauffer, H. (1958). "Gebirgsklassifizierung für den ...
Leopold Müller at the Geomechanik Kolloquium 1966 in Salzburg, Austria. Leopold Müller (born 9 January 1908 in Salzburg, died 1 August 1988 in Salzburg) was a geologist, one of the pioneers of rock mechanics and one of the main contributors to the development of the new Austrian tunneling method (NATM).
All tunnels are built with the New Austrian tunnelling method, and a number of challenges have been encountered while tunnelling through the geologically young, unstable Sivalik Hills. In particular, water entered the Udhampur-to-Katra section; this required drastic solutions with steel arches and several feet of shotcrete .
Ladislaus von Rabcewicz (June 12, 1893 in Kungota, nearby Maribor – December 19, 1975) was an Austrian engineer and university professor at the Vienna University of Technology. He is notable for being one of three men who developed the new Austrian tunneling method (NATM).
