GEOTECHNICAL PARAMETERS AND THEIR RELATIONSHIP TO ROCK RESISTIVITY
Electrical resistivity is controled in large part by the amount of fluid filled pore volume in a rock. Rock strength and other geotechnical parameters are also affected by porosity, among other factors. The mutual dependence of these seemingly unrelated properties upon a common controlling factor explains predictable and demonstrable correlations which exist between them. These correlations suggest that resistivity measurements can be used as a qualitative guide in evaluating an area as to its engineering properties. The advantage of using resistivity measurements lies in the fact that they can be made more rapidly and cheaply than direct or other indirect methods of determining engineering rock properties. This fulfills a need for a technique to classify large areas of ground, with respect to their engineering properties, at an early reconnaissance stage in selecting sites for installations that require special strength characteristics in the earth.
