The STUVA regularly promotes tunnel forums at the InnoTrans Convention involving high-grade podium discussions and rounds of experts. Here at international level the emphasis is on what will keep us mobile in future. The article presents the programme of this year’s Tunnel Forum.
Since the Scheibengipfel Tunnel with a length of 1.9 km was opened for traffic on October 27, 2017, the city centre of Reutlingen (Germany) has had to cope with as many as 20 000 fewer vehicles. This...
Increasingly complex requirements with regard to safety equipment are creating a desire for simple and practical solutions among tunnel constructors and operators. For example, the legal requirements...
With the Multi-Monti screw anchor, German fastening specialist Heco from Schramberg in the Black Forest supplies a product for fastenings in concrete which offers numerous benefits compared to drop-in...
Against the background of a large number of fires with a tragic outcome, legal regulations on safety in tunnels have been drastically tightened in Europe. Structural provisions are intended to ensure that in the event of fire neither damage occurs to the tunnel affecting its stability nor permanent deformations produced to restrict the tunnel’s serviceability. Structural joints, which are planned and executed to cope with movements, deserve particular attention in such cases.
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).
The Semmering Base Tunnel (SBT) is currently under construction and is one of the most important major infrastructure projects in the heart of Europe, forming part of the new Austrian Southern Railway...
Das Baustellenteam um die Tunnelbohrmaschine „Käthchen“ hat Anfang Juni die zweite Röhre des Boßlertunnels fertig gestellt. Der Durchbruch nahe Mühlhausen im Tale in Baden-Württemberg ist ein weiterer...
