Fasani, Martina; Ammann, Eduard; Rüttimann, Markus | Tunnel San Fedele | Geomechanics and Tunnelling | 2/2012 | 135-148 | Topics |
AbstractThe Roveredo bypass project will divert the national road A13 away from the village and includes three construction sections. The heart of the Roveredo bypass is the 2,391 m long two-lane San Fedele Tunnel, which will carry traffic in both directions. Parallel to the tunnel, a safety tunnel is being constructed with an excavation diameter of 4 m. This will be linked to the tunnel every 300 m. x | |||||
Erben, Hartmut; Galler, Robert | Tunnel spoil - New technologies on the way from waste to raw material / Tunnelausbruch - Neue Technologien für den Weg vom Abfall zum Rohstoff | Geomechanics and Tunnelling | 5/2014 | 402-410 | Topics |
AbstractConsidering the increasing shortage of resources, the reuse of material excavated from tunnels is the order of the day, which is being followed by clients, consultants and contractors as well as lawmakers. In addition to the creation of a legal situation to enable efficient and unbureaucratic reuse, further technical developments are also required in relation to material analysis to enable an immediate characterisation of the material at the face according to the decisive parameters for reuse. The linking of these results with a raw material database, in which the results of the material analyses are stored, represents a step towards modern, web-based handling of mineral raw materials. x | |||||
Mlinar, Christian; Sempelmann, Franz; Koch, Gerhard; Steiner, Michael; Kubin, Florian | Tunnel spoil as a source of raw materials for an autobahn - Sustainable reuse of resources through the example of the S 10 / Tunnelausbruch als Rohstoffquelle für eine Autobahn - Nachhaltige Ressourcenverwertung am Beispiel der S 10 | Geomechanics and Tunnelling | 5/2014 | 428-436 | Topics |
AbstractThe construction of autobahns and dual-carriageway roads is only possible with considerable use of resources and visible encroachment in the environment and landscape. The ASFINAG is aware of their responsibility for this, so modern and resource-saving construction materials and methods are being used for the new building of federal roads. This also includes the intention to balance masses on the overall project and the best quality management of tunnel spoil. A good collaboration of technical design and environmental design with clarification of the potential for material recycling and the necessary approvals are preconditions for sustainable materials management. Nevertheless, the implementation of major projects like the S 10 Mühlviertler Schnellstraße (S 10) is faced with challenging conditions, which complicate efficient and sustainable handling of materials. x | |||||
Reichel, Paul | Tunnel spoil: Tipping or the end of the definition as waste / Tunnelausbruch: Deponierung oder Abfallende | Geomechanics and Tunnelling | 5/2014 | 419-427 | Topics |
AbstractTunnel construction normally results in the production of large quantities of broken rock or soil. One essential question for the legal handling of this tunnel spoil is whether it is considered to be waste under the terms of European and national waste laws. The current paper therefore looks into the practically important question, under what preconditions tunnel spoil is legally considered to be waste and when the end of this property is reached. In this regard, it is first investigated whether and when tunnel spoil is waste under the terms of the Waste framework directive 2008/98/EC. Particular attention is paid to the applicable case law of the European Court of Justice (ECJ). Then the question is asked, to what extent tunnel spoil can be regarded as material excavated in the course of construction works under the terms of Art. 2 Sec. 1 lit. c of the waste directive, and is thus excepted from the scope of application of the directive. Finally, it is explained how the possible property of tunnel spoil as waste can end, including details of both the EU requirements and also national law. x | |||||

Incecik, Mete; Po luk, Evren | Tunnel T26 on the Ankara-Istanbul high speed rail route - Tunnelling under difficult conditions / Der Tunnel T26 auf Schnellstrecke Ankara-Istanbul - Vortrieb unter schwierigen geologischen Verhältnissen | Geomechanics and Tunnelling | 5/2018 | 434-440 | Topics |
AbstractThe Turkish Railway Administration has started to renovate and modernise the Turkish railway network in Anatolia after a long break. As the first task, a high speed railway line has been planned between the capital city Ankara and the commercial metropolis Istanbul. The section between Bozoyuk and Bilecik passes through a steep mountain range, where the old railway line and the existing highway are located right next to each other. The rail line for the new high speed route is planned to run over the steep valley of Bozoyuk and then connect to Tunnel T26. This region has a quite old geological composition with metamorphic silt and clay shales, which are folded over each other due to tectonic movement. The shales are crushed down to small pebble-cobble sized particles, significantly reducing the cohesion. The excavation work for Tunnel T26 was conducted under arduous conditions due to inadequate geological investigation. x | |||||
Baumann, Th. | Tunnelauskleidungen mit Stahlbetontübbingen. | Bautechnik | 1/1992 | 11-20 | Fachthemen |
AbstractFür die wasserdichte Auskleidung von Tunneln, die in Schildbauweise vorgetrieben werden, sind einschalige Stahlbetontübbinge eine gute und wirtschaftliche Lösung. Die Tübbing -Konstruktion ermöglicht aber erst in Verbindung mit der richtigen Vortriebstechnik die einwandfreie Herstellung solcher Tunnelauskleidungen. Ebenso wichtig wie die konstruktiven und maschinentechnischen Konzepte sind erfahrene, gut geschulte Vortriebsmannschaften, die diese Konzepte unter fachkundiger Leitung in die Realität umzusetzen. Der vorliegende Beitrag berichtet über entsprechende Erfahrungen und Entwicklungen. Bei der Vortriebstechnik sind Schildsteuerung, Ringauswahl, Tübbbingmontage und Ringspaltverpressung von besonderer Bedeutung. Die beim Baulos Wöhrder Wiese der U-Bahn Nürnberg mit Erfolg eingesetzten Konzepte werden vorgestellt. Bei der Tübbing-Konstruktion kommt es u.a. auf die Formgebung und Verschraubung der Fugen und auf die Bewehrung an. Die Erfahrungen reichen hier vom Rheindüker Düsseldorf, der vor über 30 Jahren gebaut wurde, bis zum Eisenbahntunnel unter dem Großen Belt. Grundsatzuntersuchungen zum Tragverhalten von Tübbingfugen stellen die Verbindung zwischen Theorie und Praxis her. x | |||||

Girmscheid, G. | Tunnelbau im Sprengvortrieb - Rationalisierung durch Teilroboterisierung und Innovationen | Bautechnik | 1/1998 | 11-20 | Fachthemen |
AbstractDer Tunnelbau mittels Sprengvortrieb kombiniert ingenieurgeologische und kunstruktive Konzepte mit handwerklichen Arbeitsmethoden. Trotz hoher Mechanisierung sind die Rationalisierungspotentiale bei weitem nicht ausgeschöpft. Zur Weiterentwicklung der Leistungssteigerung und der Kosteneffizienz dieser Vortriebsmethode und zur Erhöhung der Arbeitssicherheit ist es erforderlich, die einzelnen baubetrieblichen Systeme der Arbeitsprozeßkette hinsichtlich Effizienzsteigerung näher zu untersuchen. Es werden mögliche Innovationen im Rahmen der Sprengtechnik und der Teilroboterisierung der Betriebssysteme aufgezeigt, die in Zukunft weiterentwickelt werden sollten. In diesem Beitrag wird der ganzheitliche Zusammenhang zwischen gewählter Konstruktion, Sicherungssystemen und dem rationellen Einsatz von teilroboterisierten Systemen veranschaulicht dargestellt. x | |||||

Goger, Gerald; Bisenberger, Tobias | Tunnelling 4.0 - Construction-related future trends / Tunnelbau 4.0 - Baubetriebliche Zukunftstrends | Geomechanics and Tunnelling | 6/2018 | 710-721 | Topics |
AbstractThe digitalisation of construction-related processes will increasingly penetrate the individual development phases of tunnel construction projects (design, construction and operation). The digital transformation will affect all tunnelling processes through its four key levers: “digital data, automation, networks and digital access”. Topics such as Industry 4.0, digital twins, Building Information Modelling or Lean Management will lead to a rethink in the construction industry. The constant use of data sources and the storage of data in independent databases is already possible. This makes it possible for the project participants to analyse collected construction-related data, to process it and to make it available through an online portal. This results in the possibility to evaluate, optimize and document construction processes on a well-founded data base. Complex construction management systems will be described with digital models, and the use of digital knowledge systems will support the decision-making process for stakeholders. The fundamental philosophy of the New Austrian Tunnelling Method should not be called into question by standardised calculation algorithms and tunnelling software. In this contribution, visionary future trends are outlined for cyclical and continuous tunnelling methods, which should stimulate a controversial discussion. x | |||||
Gradnik, Richard; Kicherer, Manfred; Zwick, Markus | Tunnelling for the third section of the Stadtbahn line U12 in Stuttgart / Der Vortrieb für den dritten Teilabschnitt der Stadtbahnline U12 in Stuttgart | Geomechanics and Tunnelling | 5/2014 | 481-490 | Topics |
AbstractUnder contract to SSB, the urban rail operator in Stuttgart, Alfred Kunz Untertagebau München has been working on the Waltraud Tunnel since February 2014, which is the key structure in the extension of the U12 in the third section from Hallschlag to the Aubrücke bridge. This tunnel, with a length of 200 m, is mostly being constructed in fill material. The greatest challenge will be to tunnel beneath a 150 year old railway embankment with less than one diameter cover under continued operation. x | |||||
Duangsano, Ochok; Yensri, Phatharaphong; Chayaroon, Arthit; Timpong, Sahaphol; Jongpradist, Pornkasem | Tunnelling impacts and mitigation on existing structures for Bangkok MRT Orange Line | Geomechanics and Tunnelling | 3/2023 | 272-280 | Topics |
AbstractThe Bangkok MRT Orange Line East Project consists of 6 km long twin tunnels and seven stations. The tunnel alignment runs along one of the most congested road corridors of the city. Due to adverse conditions of limited road right of way, obstructions from existing structures such as buildings, infrastructure, tunnels, and other utilities, the design and construction of the tunnel require careful consideration and implementation of excavation works to limit excessive ground movements and mitigate the potential impacts on existing structures. This article presents the concepts and procedures in detail on assessing the impact on each type of adjacent structure due to tunnel construction which contribute to the successful completion of the MRT Orange Line Project. Additionally, some mitigation measures for critical cases are highlighted. x | |||||
Gütter, Wolfgang; Rudigier, Günther | Tunnelling in Crete - A challenging task from a variety of aspects | Geomechanics and Tunnelling | 6/2016 | 636-646 | Topics |
AbstractIn 2012 the Greek State awarded Intrakat the Aposelemis Tunnel, an approx. 3.5 km long, tunnel inclined at 15% accommodating a 1.8 m diameter steel pipe to convey water from the Lassithi Plateau to the reservoir impounded by the Aposelemis dam about 600 m below for the drinking water supply of Heraklion and Agios Nikolaos in Crete. The project is regarded as an environmental project and as such is being financed from the Cohesion Fund of the European Commission. Unexpectedly, this relatively small tunnel project has offered a wide spectrum of tunnelling problems and turns out to be a challenging task from a variety of aspects: the tender and the contractual situation, technical and the meanwhile encountered geological challenges. On top of these, the economic crisis in Greece doesn't make such a project easy. Since October 2013, Jäger Bau GmbH has mastered these challenges together with Intrakat on the basis of a service contract. The TBM excavation works commenced in March 2015 and were expected to be completed within 11 months at the latest, but due to various unforeseen adverse geological occurrences, only two-thirds of the tunnel length had been excavated by August 2016. x | |||||
Gamper, C.; Theurl, M. | Tunnelling in Hungary - The M6 chain of tunnels / Tunnelbau in Ungarn - Tunnelkette M6 | Geomechanics and Tunnelling | 6/2010 | 711-718 | Topics |
AbstractIn Hungary, a motorway network is being built in a star shape starting in Budapest. The M6 motorway runs southward from Budapest towards Croatia and will also link the city of Pécs, the European Capital of Culture for 2010 to the network. A consortium consisting of the firms Strabag, Colas, John Laing and Intertoll were awarded a contract in autumn 2007 to design, build and operate a section with a length of 48 km. An important part of the works is the construction of the M6 tunnel chain consisting of four twin-bore, two-lane motorway tunnels. These tunnels were built by Strabag. During the driving of the longest tunnel, a collapse occurred in summer 2008, in which both tunnel bores caved in over a length of 200 m. The lecture reports on the driving of the tunnel through the collapsed area and the construction of the subsequent inner lining works, which made it possible to maintain the opening date. x | |||||

Zettler, A.; Poisel, R.; Preh, A.; Konietzky, H. | Tunnelling in swelling rock - a solved problem? / Vortrieb in quellendem Gebirge - ein gelöstes Problem? | Geomechanics and Tunnelling | 5/2010 | 557-566 | Topics |
AbstractIn some sedimentary rocks, the admission of water results in an expansion of volume, which results from the chemical conversion of anhydrite into gypsum (anhydrite swelling) or the physical adsorption of water in certain clay minerals (clay swelling). This expansion leads to heavy loading of the tunnel lining and has already caused significant damage to some structures. In addition, sulphate attack on the lining concrete can lead to softening due to the formation of ettringite. Damage can be in the form of shear failure, spalling or bending tension cracks. The location and nature of the damage, which depends on the location of the ground containing clay or anhydrite and susceptible to swelling, is illustrated with some examples. Numerical modelling is applied to demonstrate the load transfers, which lead to these phenomena. Recent attempts to counter the problem have been based on the strengthening of the lining (resistance principle) or by installing compressible zones between rock mass and lining (yielding principle). The design rules for each principle are explained. x | |||||
