Abstract
The use of microfibre shotcrete eliminates the need to use steel reinforcement in construction of primary support in tunnels and so potentially brings huge savings. It is imperative to better define the means and conditions of the production of microfibre shotcrete and to resolve favourable geological conditions for its application, especially so in tectonically reworked rocks. The PRR activities involve the following: selection of the in situ research filed during the construction of the tunnel respecting different geological conditions, sampling and laboratory testing of rock mass to establish the governing stiffness-strength parameters, application of the testing microfibre shotcrete into primary lining, sampling and laboratory testing of microfibre shotcrete to establish its tension capacity and, finally, in-situ measurements of the behaviour of the primary lining. In parallel with these activities the financial efficiency of the use of microfibre shotcrete will be compared with common methods.
