Structural SFRC for Precast Segments of the Tunnel Lining
Original language description
The paper is focused on the strength parameters of the designed structural steel fibre reinforced concrete (SFRC), which are important for the resisting capacity of the tunnel lining segments and their damage during manipulation. Generally the segments are more loaded during tunnel lining installation (long term load is lower). The realised investigation was focused on SFRC with various dosages of steel fibres, two types of fibres were tested. One of the reasons of the testing was also fixed low thickness of the segments (only 250 mm). Structural SFRC with fibre dosages 50 kg/m3 and 70 kg/m3 were tested (i.e. dosages recommended by authors of this texts considering low thickness of the segments and their high temporary load). The paper also includes results of testing of two different key segments (ordinary RC key segment and SFRC key segment with fibre dosages 50 kg/m3).
