Abstract :
This paper explores the use of diametrically
aligned vertical electric sounding VES in assessing
homogeneity and anisotropy in layered sedimentary soils
and in weathered rock formation. Both Wenner and
schlumberger electrode configurations were used in the
sedimentary and weathered rock formation respectively,
and augmented by geotechnical boring to 30m. The
Mann-Whitney U-test was applied to the diametrically
aligned VES data where the presence of significant
differences between the data sets suggested degrees of
uniformity in ground resistivity and by extension
compositional quality and structure. Similarly,
characteristic values of electrical resistivity in
diametrically opposite directions of the geo-layers were
determined and compared. By evaluating the differences
in apparent resistivity at the same depth, a measure of
homogeneity was derived. Various degrees of
homogeneity were established at both the sedimentary
and weathered formation.
