Résumé

The planned construction of traffic routes through the European Alps represents a challenge for science and technology. In the past decades, Austria has gained a leading position in the field of tunnelling. This has been verified by many successful projects all over the world, which have been realised with the well-known "New Austrian Tunnelling Method".

However, further development and economic success of modern tunnelling methods, which are still partly based on empirical assumptions, can only be assured if their scientific basis is improved. The book discusses the application of numerical simulation methods to assist tunnel engineers. Numerical simulation tools for the estimation of the required tunnel support and the required construction measures are described in this book.

By using them, it is possible to study the impact on construction and environment during the planning stage and during construction. This will result in an improvement of the safety and economy of tunnels.
