Table 1 Correlation between ERT and well data using the specific values range of resistivity and Kv for rock mass quality evaluation.
From: Application of electrical resistivity tomography (ERT) for rock mass quality evaluation
Resistivity (Ωm) | Kv | Rock mass quality | Site suitability for infrastructures |
|---|---|---|---|
< 1000 | 0–0.15 | Weathered/crushed rock | Unsuitable |
> 1000 | 0.55–0.75 | Fresh/integral rock | Suitable |
