Abstract
A study is made of a newly-developed differential electric field (DEF) method, wherein potentials between potential electrodes equidistant from a current electrode is measured for directly detecting the secondary potential attributable to an anomalous-resistivity body. In this method, a current is fed into the ground from a point source C1, and four potential electrodes, two each on the X-axis and Y-axis, are provided equidistant from the point source C1 for the measurement of the potentials in the directions of X and Y. Numerical experiments and field experiments in a playground were conducted for this DEF method, and it was found that this method is effective in detecting an anomalous-resistivity bodies (ruins, etc.) situated in a homogeneous medium or in a horizontal multi-layer structure, is capable of displaying anomalous vectors enabling the estimation of the direction from the observation point of the anomalous-resistivity body, improves on work efficiency over the conventional mapping method, enables the estimation of the boundary of the anomalous-resistivity body on the basis of the peak of the anomalous electric field residue on the display, and that the obtained data can be easily processed by use of a personal computer on the site. 3 refs., 9 figs.
