    Abstract: Risk management became an integral part of most underground construction projects during the last decade. Still, there are parties, who may not plan for insubstantial unknown uncertainties of ground conditions because they are so unpredictable and out of scope of normal planning as they think. Finally, many of them end up as the most catastrophic events. Even known geological uncertainty is a...

    Abstract: The knowledge of the geological ground conditions and its geotechnical parameters is still the major problem for driving of a tunnel. Although, underground construction works are increasingly carried out under difficult soil and rock conditions. Significant geological boundaries that cut the tunnel axis can cause serious problems such as large break-outs, collapses, flooding and rush-ins during...

    Abstract: Tunnel seismic prediction while excavation is an attractive technology for underground rock mass characterisation due to the short downtime needed for data acquisition and fast data processing and evaluation. By recording the full wave-field of reflected signals, prediction of the rock mass quality up to 200 m ahead of the face is possible and 3D velocity distribution images can be generated by...
