Abstract: The objective of this paper is to investigate a particular tunnelling method, known as the New Austrian Tunnelling Method (NATM), which first appeared in English publications in 1964. NATM was described as a modern tunnelling method by Rabcewicz. Throughout the literature survey, there have been encountered numerous ambiguities and conflicts relating to the NATM. Furthermore, researchers who devoted themselves to tunnelling technology are split into three groups. These are the supporters of the early precursors of the NATM as a new modern tunnelling method (Müller 1978; Golser 1979), the opponents as nothing new and Austrian, and the neutral group. The ultimate criticism against NATM, denying its existence, has been made by Kovári (1994). The applications of this method, however, have accelerated all over the world due to its overwhelming beneficial features compared with other conventional tunnelling methods. Sometimes, NATM is referred to using different titles such as Sprayed Concrete Lining (SCL) (ICE, 1996), Sequential Excavation Method (SEM) as distinct from NATM (Brandt et al. quoted by ICE 1996), CDNATM, Centre Dividing wall NATM (Kobayashi et al. 1994), CDM, Centre Diaphragm Method (Seki et al. 1989) or CRD-NATM, Cross Diaphragm Method (Narasaki 1989) and UHVS, Upper half vertical subdivision method (Seki et al. 1989). Detailed definitions for NATM are available in the literature and the historical background with characteristic features will be discussed in paper.
