The base tunnels on the new rail links passing through the Alps (NRLA) are planned to last for more than one hundred years. High requirements were posed regarding permissible risks and fault frequency so that the railway engineering equipment functions as safely and reliably as possible. The fulfilment of these requirements must be documented by the contractor by means of secured predictions. RAMS technology forms the basis for this in keeping with CENELEC Standard 50126, which has been applied in its entirety for the first time for infrastructure projects of this magnitude.
Southeastern Turkey’s Gaziantep province is characterized by complex fractured rock within the Eastern Anatolian Fault, and it is now the location of an important railway tunnel project. With a population of nearly 1.7 million, the province is overhauling its public transportation with a rail line between the towns of Bahçe and Nurdağı. The Bahce–Nurdag Railway Tunnel consists of two parallel 9.75 km tunnels being excavated by both the New Austrian Tunnelling Method/NATM (850 m) and tunnel boring machine/TBM (8.9 km).
