  On-Site Visualization as a new monitoring scheme for tunnelling engineering

  Abstract: This paper proposes a new monitoring scheme which is characterized by use of new type of instruments capabe of not only processing data, but also visually outputting them for immediate recognition of measured information by vision. Therefore, time required for all workers to notice occurrence of an event could be as small as the theoretical speed limit for data transmission, namely the speed of...

  Surface Monitoring of Tunnel Faces and Improvement of Face Work Safety by ICT

  Abstract: We report a method to assist in monitoring the working face in mountain tunnel construction by applying information and communication technology (ICT) to the measurements. The whole working face was monitored from the three-dimensional point group data provided by laser measurements of the surface. Technology which assists the monitoring supervisor in assessing the working face by the face was...
