Research ArticleOpen accessIn the author namesCeppo Morelli Block-Falls Probability Study to Support the Decision of Excavating a by-Pass TunnelS. Longo, P. OresteProblem statement: In this article, some important aspects linked to the new Ceppo Morelli (Piemonte, Italy) future by-pass tunnel construction were considered. Approach: The article concerned a mountainous region which in the past was affected by slope landslides and block falls that reached a downhill roadway and two nearby villages. Results: Using risk analysis approach the probability of block-falls down … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,684 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalysis 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
Research ArticleOpen accessIn the author namesThe Tunnel Boring Machine Advancements in Horizontal and Up-Hill TunnelsStefano Fuoco, Pierpaolo OresteProblem statement: Nowadays high levels of experience have been acquired in the excavation of horizontal tunnels using TBM, especially as far as tunnels with small diameters (about 4 m wide) are concerned. Less experience has been acquired in the excavation of tunnels under difficult alignment conditions, as in the case of steeply inclined excavations (up-hill tunnels). Approach: This study presented … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,848 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Convergence-Confinement Method: Roles and Limits in Modern Geomechanical Tunnel DesignPierpaolo OresteThe convergence-confinement method, based on the analysis of the stress and strain state that develops in the rock around a circular tunnel, has been presented in this study with the two analytical solutions that have been most frequently used in recent years. Problem statement: Thanks to the increased power of electronic processors and the spread of numerical methods, the role … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 10,151 accessesView PDFCite
