Abstract

Between 75 and 100 kilometres of tunnel are excavated in Norway each year. In many of these tunnelling projects, the contractor is looking for methods to acquire geological information during the excavation process, enabling him to carry out the project safely and in a cost effective manner. Often the contractor would like to know the geological situation ahead of the tunnel front or the rock thickness and quality above the tunnel.
