dcterms:description
Segmental tunnel lining is usually applied to mechanised tunnelling using full-face tunnelling shields (the TBM technology). Pre-cast steel fibre reinforced segments are currently used in praxis, containing no traditional rod reinforcement. In the Czech Republic, there is a research underway focused on problems of steel fibre reinforced segments so that this technology can be applied even to Czech tunnels. A variety of samples were produced and tested in the initial phases of the research, serving for the comparison and selection of suitable composition of steel fibre reinforced concrete mixture. The influence of different dosing of steel fibres on the resultant behaviour of steel fibre reinforced concrete was subjected to comparison. The properties of steel fibres were laboratory tested and assessed (unconfined compressive strength tested on cubes, flexural strength tested on beams). Some parameters of steel fibre reinforced concrete were derived backward by means of advanced numerical modelling using the Finite Element Method in the ANTENA simulator. Traditionally reinforced concrete segments and SFRC segments were tested by the Klokner's Institute of the Czech Technical University in Prague. The results of the completed tests are presented in the paper. Segmental tunnel lining is usually applied to mechanised tunnelling using full-face tunnelling shields (the TBM technology).
