Master thesis
Open AccessEn el diseño de túneles en roca, excavados mediante el Nuevo Método Austríaco, es bien conocida la importancia que tiene el drenaje y la permeabilidad del macizo en la estabilidad tensional del mismo. En algunos casos se ... -
Application of Barcelona test for controlling energy absorption capacity of FRS in underground mining works
(Elsevier, 2020-06)
Article
Open AccessIn recent years in Chile, the use of fiber reinforced shotcrete (FRS) has been widely extended in underground works, particularly in tunnels for roads, mines and hydroelectric projects. In these projects, the design of the ... -
Crack width design approach for fibre reinforced concrete tunnel segments for TBM thrust loads
(Elsevier, 2020-04)
Article
Open AccessConcentrated loads induced during the excavation stage by Tunnel Boring Machines (TBMs) is still a matter of discussion into the tunnelling construction field, this having a strong impact from both the technical (e.g., ... -
Dovelas de hormigón (concreto) reforzado con fibras para el soporte de túneles y pozos verticales

Open AccessEl projecte global, el qual engloba aquest treball, tracta sobre el recobriment intern de túnels mitjançant perfils FRP, formigó i malles, trobant les millors combinacions, les millors maneres de cohesionar els materials, ... -
Experimental and analytical study of concrete blocks subjected to concentrated loads with an application to TBM-constructed tunnels
(2015-06)
Article
Open AccessTo generate enough thrust for a Tunnel Boring Machine (TBM) to excavate a soil and advance, several jacks are typically used to apply force to the last installed ring that acts as a reaction frame. These loads generate ... -
Hybrid minimization algorithm applied to tunnel back analysis
(CRC Press Taylor & Francis Group, 2014)
Conference report
Restricted access - publisher's policyThe paper describes a procedure to perform backanalysis in an automatic manner in the context of a tunnel excavation. The measured displacements are compared with the calculated ones obtained from a Finite Element Analysis, ... -

Seismic fragility curves for vulnerability assessment of steel fiber reinforced concrete segmental tunnel linings
(Elsevier, 2018-08-01)
Article
Open AccessIn recent years, application of fibers as a replacement for conventional reinforcement in segmented lined tunnels has gained great interest due to resulting cost and time savings. In seismically active regions, the seismic ... -
Sustainability based-approach to determine the concrete type and reinforcement configuration of TBM tunnels linings. Case study: Extension line to Barcelona Airport T1
(2017-01)
Article
Open AccessFibre-reinforced concrete (FRC) is a suitable alternative to the traditional reinforced concrete used in the manufacture of precast segments used to line tunnels excavated with a tunnel boring machine (TBM). Moreover, its ... -
Use of tire derived aggregate in tunnel cut-and-cover
(2017-11)
Article
Open AccessA case-history is reported in which tire derived aggregate (TDA) was successfully applied to reduce the weight of fill upon a cut-and-cover railway tunnel. Subsequent 3D numerical analyses are used to explore the effect ... -
