As a consequence they have always occupied a subordinate position with respect to similar surface constructions and in the past they were only resorted to when the latter seemed impractical or of little use. However, decisive progress made in the feld of geological surveys, the availability of powerful computers for making calculations and above all the introduction of exca- tion technologies that are effective in all types of ground have created the conditions for a qualitative quantum leap forward. The last formidable negative factor to be overcome to achieve that transparency in this feld, which has until now been the prerogative of traditional surface works, remains the absence of a modern and universally valid design approach, capable, that is, of integrating and exploiting the new capabilities and of gu- i | 出版日期 | Book 2008 | 关键词 | Deformation Response; Diagnosis; Response Control; Therapy; Verification; deformation; safety; stress | 版次 | 1 | doi | https://doi.org/10.1007/978-3-540-73875-6 | isbn_softcover | 978-3-662-51834-2 | isbn_ebook | 978-3-540-73875-6 | copyright | Springer-Verlag Berlin Heidelberg 2008 |
