Research ArticleOpen accessIn the abstractTunnel Static Behavior Assessed by a Probabilistic Approach to the Back-AnalysisClaudio Oggeri, Pierpaolo OresteProblem statement: The steps of the validation procedure of the project of a tunnel are briefly illustrated in this study, starting from the geological and structural surveys on the excavation walls and the measurement of the physical and mechanical parameters during the excavation works. Unfortunately, however, the knowledge of the rock mass, which is fundamental to the project, is usually … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractMost Used Rock Mass Classifications for Underground OpeningAl-Jbori A’ssim, Zhang Y. XingProblem statement: Rock mass characterization is an integral part of rock engineering practice. The empirical design methods based on rock mass classifications systems provide quick assessments of the support requirements for underground excavations at any stage of a project, even if the available geotechnical data are limited. The underground excavation industry tends to lean on empirical approaches such as rock … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Tunnel Boring Machine Advancement on the Bologna-Florence Railway LinkM. Cardu, P. Oreste, T. CicalaProblem statement: The high-velocity railway link between Bologna and Firenze (Italy) is today under construction and several tunnels have to be excavated for this purpose, some of these using TBMs. A small diameter tunnel, named Cunicolo ginori, was realized by TBM parallel to a large railway tunnel (Vaglia), at the distance of only 35 m. Approach: The Vaglia tunnel had … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Sep 2009 · 7,963 accessesView PDFCite
