Mechanised shield tunnelling / Проходка тоннелей механизированным щитом

The rapid progress of mechanised tunnelling to market leadership has continued – even exceeded predictions; the general worldwide trend in construction towards mechanisation and automation clearly demanded a similar development in tunnelling. It is significant that even in Austria, the traditional home of the New Austrian Tunnelling Method (NATM), mechanised tunnelling has also established its position in the last decade. Occupational health and safety, faster advance rates, improved cost security and labour-saving opened opportunities for mechanised tunnelling on a few major projects – normally in competition with conventional construction methods. So it is appropriate that this book should now be revised, 20 years after its first publication. The extent of innovations and practical experience led to a complete reworking. Incidentally, the book “Hardock Tunnel Boring Machines“, which appeared in 2008, already offered access to the newest technology in the area of tunnel support. The team of authors has adapted the content to the latest technology and has been supplemented to provide the necessary specialist knowledge.
The original authors B. Maidl and M. Herrenknecht also worked on this edition. We have gained my son Dr.-Ing. U. Maidl and my former doctoral candidate Dr.-Ing. G. Wehrmeyer, who have particularly devoted themselves to new developments. I am very thankful that I could still rely on the help of my former employees Herr H. Schmidt and Herr G. Kaufhold for the new revision. I would like to thank Herr Dipl-Ing. M. Griese from MTC, who helped a great deal with the detailed work and overall coordination. I would also like to thank my grandson Max Maidl for his assistance. A thank-you to all, especially the author colleagues and the publisher. <...>
