Abstract

Summary

The aim of our study is to assess whether resistivity may be transformable into an engineering parameter such as the Q-value and can substitute seismic investigation when not practicable. ERT has the advantage of being efficient, reliable, silent and non-destructive, therefore suitable in urban areas.

We have integrated Q-values derived from core drillings and geological logging during tunnelling and resistivity derived from surface ERT on two tunnel projects in Norway. In both cases, it is qualitatively evident that lower resistivity points towards weaker rock. Indeed, preliminary results can partially show the expected correlation where resistivity data co-align with boreholes or the tunnel.
