  Correlating rock support and ground treatment means with in -tunnel seismic data

  Abstract: Tunnelling is a challenging task since it demands recurrent interaction and good understanding of the various disciplines of geotechnical engineering, geology and geophysics among others. Moreover, during tunnel excavation quantitative and qualitative data is continuously gathered by instruments and personnel from all these disciplines. Finding and understanding correlations between such...

  Tunnel seismic investigations at low overburden in subsea tunnels

  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...
