KurzfassungDer Brenner Basistunnel verläuft von der Umfahrung von Innsbruck bzw. vom Innsbrucker Bahnhof nach Franzensfeste mit einer Länge von 55 km. Mit der Umfahrung Innsbruck beträgt die Gesamtlänge 62, 8 km, womit er zum längsten Eisenbahntunnel der Welt wird. Zwei parallel verlaufende Tunnelröhren mit einem etwa 12 m tiefer liegenden Erkundungsstollen kennzeichnen diesen Basistunnel. Zur baubetrieblichen Risikominimierung des Basistunnels, insbesondere jene Anteile die mit Tunnelvortriebsmaschinen vorgetrieben werden sollen, sind systematische Erkundungen mittels eines Stollens von großer Bedeutung. Derzeit wird am 10 km langen Erkundungsstollen Aicha - Mauls mit einer Tunnelbohrmaschine gearbeitet. Der Ausbau erfolgt mit dünnwandigen Betontübbingen. Dort werden auch spezielle Monitoringpunkte angebracht. Die Querschnittsoptimierung der Tübbinge, die betontechnologischen Studien und die geeigneten Bereiche für das Monitoring werden dargestellt. x | |||||
Skuk, Stefan; Schierl, Heimo | Brenner Base Tunnel: First results of the exploratory tunnels from a geological and geomechanical point of view - Case studies of four fault zones | Geomechanics and Tunnelling | 3/2017 | 275-290 | Topics |
KurzfassungThe Brenner Base Tunnel (BBT) is a straight, flat railway tunnel between Austria and Italy. It runs from Innsbruck to Fortezza (55 km), crossing the main Alpine crest with an overburden up to 1.7 km. Including the connection to the line around Innsbruck, which has already been built and which is the endpoint for the BBT, the total length of the tunnel will be about 64 km. Once finished, the BBT will be the longest underground rail link in the world. A peculiar feature of the BBT is the exploratory tunnel running from one end to the other. This tunnel lies between the two main tunnels and about 12 m below them and is noticeably smaller than the main tubes. So far, a total of 60 km of tunnels have already been excavated in Austria and Italy (access tunnels, exploratory tunnel, main tubes and chambers), driven both by blasting and by TBM. Crossing fault zones is a geological and geomechanical challenge, both for TBM and conventional excavation methods. The Periadriatic fault zone, with a total length of 1 km, has already been driven through. This first step of the project provides an interesting look at the comparison of the predicted rock mass conditions with those that were actually encountered, the rock mass behaviour in fault zones and investigation measures ahead of the tunnel face. x | |||||
Flora, Matthias; Grüllich, Sebastian; Töchterle, Andreas; Schierl, Heimo | Brenner Base Tunnel exploratory tunnel Ahrental-Pfons - interaction between tunnel boring machine and rock mass as well as measures to manage fault zones / Brenner Basistunnel Erkundungsstollen Ahrental-Pfons - Interaktion zwischen Tunnelbohrmaschine und Gebirge sowie Maßnahmen zur Ereignisbewältigung in den Störzonen | Geomechanics and Tunnelling | 5/2019 | 575-585 | Topics |
KurzfassungApprox. 42 km of tunnel were excavated on the contract Tulfes-Pfons H33, including a 15 km long section of the exploratory tunnel, which has been excavated since October 2015 with a gripper TBM from the Ahrental access tunnel southward into the district of Steinach. The interaction of the tunnel boring machine with the rock mass is discussed here as a back analysis of the mechanized tunnelling drive. This article does compare the forecast with the actual geological/geotechnical conditions, but only considers the conditions actually encountered. The back analysis takes place analogously to the principle of geotechnical planning according to the ÖGG (Austrian Society of Geomechanics) guideline, in which, starting from the rock mass structure and the rock mass types, the encountered tunnel face and intrados behaviour are observed and an estimation of the system behaviour is carried out. A description of the tunnelling technology concept completes this paper together with two case studies and the lessons learned. x | |||||

KurzfassungThis report deals with tunnelling over and under existing tunnels with unreinforced concrete linings and tunnelling under an existing tunnel only supported with shotcrete. The uppermost task was to avoid damage to the existing tunnel and this could be fulfilled through carefully staged advance steps, technically correct construction by the contractor and a dense observation network. The experience tunnelling over an existing tunnel supported only with shotcrete shows that despite slight deformation, cracks and spalling occurred to the shotcrete support layer of the tunnel beneath. This damage did impair the serviceability of the support layer although the structural safety of the tunnel was never in danger. The impairment of the serviceability was temporary and could be remedied by installing overhead protection. In the long term, repair measures were necessary to the support layer in zones with poor geological conditions. x | |||||
Skuk, Stefan; Wegscheider, Daniel | Brenner Base Tunnel - a 10.5 km double shield TBM drive in granite / Brenner Basistunnel - 10,5 km Doppelschild-TBM im Granit | Geomechanics and Tunnelling | 3/2015 | 221-238 | Topics |
KurzfassungThe Brenner Base Tunnel, with two main bores and an investigation tunnel running parallel in the middle, crosses the main ridge of the Alps beneath the Brenner Pass and the border of Austria and Italy. The first construction contract was a 10.5 km long investigation tunnel bored by a double shield machine in granite. Numerous investigation measures, laboratory tests and geological face surveys were carried out, and the TBM data was recorded on a 10-second cycle. Due to the large amount of data and the very well known homogeneous geology, it seemed appropriate to develop correlations between the data of the rock mass, the rock and the TBM. Statistically reliable statements could be derived. The unconfined compression strength of the rock, discontinuity parameters and index parameters such as the RMR (Rock Mass Rating), GSI (Geological Strength Index) and RQD (Rock Quality Designation) were compared with the penetration behaviour. GSI values between 30 and 40 showed four times the penetration rate compared to GSI values between 90 and 100. This applies similarly for the RQD, RMR and discontinuity spacing values. x | |||||
