APPLICATION OF THE NATM IN DEEP TUNNELS AND DIFFICULT ROCK FORMATIONS

The article evaluates applications of the New Austrian Tunnelling Method (NATM) and considers criticisms of the technique as applied on various tunnelling projects. Interpretations of the NATM tunnel construction method are discussed in which in one case controlled rock movement is advocated while in the other, the almost complete prevention of rock movement is favoured. The significance of these approaches are discussed in relation to tunnel lining design and construction. It is concluded that tunnelling contractors must be allowed to negotiate an optimum construction procedure in their particular ground conditions to meet completion and cost requirements. (TRRL)
