Research ArticleOpen accessIn the keywordsSimplified Analysis of the Lining Behavior During Earthquakes in Deep Rock TunnelsPierpaolo OresteThe sizing of the lining of a tunnel requires to consider not only the static loads transmitted from the surrounding rock, but also the effects of earthquakes on the stresses and strains of the lining. The detailed evaluation of the interaction earthquake-lining using numerical methods typically requires very long calculation time and can be limited to the verification of the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 4 May 2015 · 6,901 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of the Interaction between the Lining of a TBM Tunnel and the Ground Using the Convergence-Confinement MethodPierpaolo OresteThe support used when a tunnel is excavated by a shielded TBM is complex because it consists of two different materials: A concrete segmental lining and a filler annulus between the lining and the tunnel wall. A detailed analysis of the behavior of such a support system requires a three-dimensional numerical modeling and should also consider the presence of the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 17 Jun 2015 · 7,183 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDEVELOPMENT OF INSPECTION SYSTEM FOR CORROSION CRACK IN R.C. FOR SECOND TUNNEL LINING BY USING KNOWLEDGE-BASED SYSTEMYousif Abdulwahid Mansoor, ZhiQiang ZhangDuring the last two or three decades, incidence of failure of reinforced concrete structures has been seen widely for many reasons, such as increasing service loads and/or durability problems and the economic losses due to such failures are costly. Nowadays, the size and the form of repair and rehabilitation market are too large since there has been an increased emphasis … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 27 Aug 2012 · 7,659 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHydrogeological Prognosis with Regard to Realisation of the New Colle Di Tenda Road TunnelCinzia Banzato, Massimo Vincenzo Civita, Adriano Fiorucci et al.Problem statement: The doubling of Tenda pass road tunnel jointing SW France to Piedmont (Italy) was planned to penetrate a complicate rock structure in which several complex play an hydrogeologic role including carbonate-Karst aquifer between flysch impervious complexes. The main problem of the project is the presence of an hydraulic circulation feeding a spring of social and economic great importance … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,363 accessesView PDF Cite
