Create lists, bibliographies and reviews: The advantage of steel-fibre-reinforced concrete segments over conventional reinforced concrete is that fibres are dispersed all over the section and hence the concrete is also there needled where those critical corner and edge zones are to be found.

In many cases, the load-bearing capacity is sufficient to eliminate entirely the need for the traditional reinforcement which otherwise would be necessary.

British Library Online Contents The drafting of the concrete recipe was a real concrete dbv-merkblaatt challenge, since it was necessary to meet both elevated durability requirements and to counteract the aggressiveness of the groundwater in the stahlfaserbrton.

Steel-fibre-reinforced segmental linings: State-of-the-art and completed projects – tunnel

Tunnel-construction methodology, which now differentiates between shotcreting and mechanised tunnelling, should firstly be examined. Preview this item Preview this item. Since this panel test determines a system load-bearing capacity, the result cannot be used for the dimensioning of individual elements e.

Extremely demanding durability requirements were defined in the dbv-merblatt to tender for this project. Serviceability is negatively affected if such spalling stahfaserbeton in water-permeability. Allow this favorite library to be seen by others Keep this favorite library private.

Your Web browser is not enabled for Stahlfaxerbeton. The frequently encountered stress-resultant combination of high compressive forces and relatively low bending moments in a tunnel lining can predominantly be matched by using the material properties of steel-fibre-reinforced concrete only. A material resistant to aggressive environment conditions was to be used, and a service-life of years to be indicated for the segmental tunnel lining rings.

Performance at low beam deflection is dbv-merkblath for analyses in serviceability limit state. Flexible systems, on the other hand, bear the loading by means, primarily, of normal forces.

Dbvv-merkblatt segments are installed as support behind the shield machine and produce a closed annular ring which, in the case of single-shell lining, is also not further supplemented. By means of the available calculation methods it is sometimes hardly possible to fugure out the ultimate material resistance, particulary if such elements are exposed to bursting and spalling forces.
