TUNNELLING OPERATIONS IN THE KATSCHBERG AND TAUERN TUNNELS FROM 1970 TO 1975

LES TRAVAUX DU TUNNEL DU KATSCHBERG ET DU TAUERN DE 1970 A 1975

The author describes the broad outline of the project and deals with: personnel and equipment deployed on the sites, geological and geotechnical conditions, drilling of different zones; use of the new Austrian method, support of the terrain and knowledge acquired which contributes to general technical progress. The use of the Austrian method resulted in an economical progress in a terrain where active earth pressure was predominant. The main characteristic of this method is that the soil around the cavity can contribute to the support of the structure by integration with the supporting arch or bearing ring. All means of support (anchorage, injection, arch added to existing tunnels, centering, metal mesh, shotcrete, metal sheeting) combine with the ring of the surrounding terrain strengthened with anchorage and injection to form a unit of great deformability, which is therefore elastic and allows for the necessary deformation of the supporting system at a reasonable cost.
