Abstract

In order to reduce the effect of any local inhomogeneity when measuring the electrical resistivity of ground, two measurements are made in different positions and an appropriately weighted average calculated. As described five electrodes are implanted in the ground at equal spacings along a straight line. An electrical current is passed through the ground between one pair of these electrodes and the potential difference between a further pair of the electrodes is measured. The electrode which is not used in this measurement is at one end of the line. A further measurement is then made with the four electrodes which exclude the electrode at the opposite end of the line. The measurements are combined to provide a measurement of apparent resistivity which is almost unaffected by a local resistivity variation.
