Publ Oxford: Pergamon Press, 1978 Describes the application of the New Austrian Tu~ing Method in soft grou~, illustrated by its use in the construction of the NUremberg, Frankfurt and Bochum subways and of the Waldeck pmmped sturage scheme, all in West Germam~. The principles of the method are s 1 ~ I s e d . The maximmn span that can be obtaiI~d by this method in soft groumd is estimated to be about 20m.
