Recent developments show that special measures like pipe umbrellas are being used more often in continuous tunnelling, and already have to be planned during the design phase. The AT - Casing System, already in successful use for some decades in sequential tunnelling and in geotechnical engineering, has recently seen increasing use in TBM tunnelling. According to the type of pipe used, the system can be used to support the surrounding ground, for grouting measures or for drainage. An example calculation is intended to demonstrate the potential of advance support over a fault zone and point out some possible optimisations of the load-bearing capacity. Finally, the system is presented through the example of the New Kaiser Wilhelm Tunnel in Germany. On this project, the AT - Pipe Umbrella System was combined with the AT - GRP Injection System in order to gain the advantages of both. © 2011 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The subject of this article based on the Kaiser Wilhelm Tunnel is the derivation of a list of criteria for overcoming critical situations during tunnelling at the borderline of open mode to closed mode operation. The consistent application of this list of criteria demonstrates, that with knowledge of the sensitive interaction of machine and surrounding ground, the scope of application of current machine technologies can even be extended into geologically difficult areas. Formerly, this led to considerable problems, at times even economic failure of the project [1] [2] [3]. The advantages the use of the catalogue of criteria has, si shown in the example of a shield machine with earth pressure components © 2011 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The 25 km long Pinglu Tunnel is part of a large water supply project in the north west of the Chinese province of Shanxi. After a brief description of the overall project, the article describes the alignment, geology, lining and the TBM and machinery concept. A second-hand hard rock double shield machine built in 1994 was supplied by the employer and had to be overhauled for the reject. During the progress of tunnelling, numerous mechanical, logistical and geological challenges had to be overcome. © 2012 Ernst & Sohn Verlag f?r Architektur und technische Wissenschaften GmbH & Co.

The Crossrail project in London, currently the largest infrastructure project in Europe, has shifted the quality control and geo - technical monitoring of SCL tunnelling to the next level. Based on the absolute priority of health and safety the chain of control spans from contract form and design to procedures and review panels on the construction site where the management, monitoring and review of significant quantities of data is a demanding task. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

If it's not safe, don't do it! Accidents at work and lost days cost a lot of money. A calculation of the consequential cost of accidents by the Allgemeine Unfall versicherungsanstalt (AUVA) estimates this at 19,128 Euro per accident in 2010. In the construction industry in Great Britain and the USA, employers and employees generally seem to attach more importance to occupational safety and communicate this more effectively than in Austria andGermany. What are the possible explanations for this difference? This article investigates basic cultural differences in general, in the safety culture and different legal traditions. The factors mentioned are not only de cisive for the usual contract and co - operation models between employer and employee in these countries but also have an effect on the sickness statistics and the cost of accidents. © 2012 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.
