<p>This paper aims to summarize all the main criteria to carry out the design and supervision of in situ concrete lining. It is shown what are the main points to make it easier the supervision. Once excavation, support and waterproofing phases are finished, ...

<p>This is a paper that discusses, in a practical/empirical manner, the movements - and their impact on the support measures- which have been measured during the excavation of the top heading of the Driskos motorway tunnel (now in operation), during the years ...

<p>A complex rheological model has been used recently at several Austrian tunnel job sites to determine stresses in a shotcrete lining. The raw data are from displacements measurements at the lining contour. The analysis uses a material model based on a thermo-chemo-mechanical ...

<p>New procedures to design cast-in-situ steel fiber reinforced concrete (SFRC) tunnel linings are briefly presented in this paper. The ductile behavior at ultimate limit stage of such cement-based structures is ensured by a suitable amount of steel fibers ...

This paper presents the only results of permanent support design for marl rock unit. Numerical modeling with a 2D finite element package was employed to simulate different loading conditions, including the surcharge load due to the mine waste expected to be ...

<p>In the course of the extension of a metro line in Vienna the station Taborstra&szlig;e will be built. Two single track platform tunnels, a connection tunnel and an elevator tunnel will be driven through sediments following an NATM excavation scheme with ...
