| Abstract: | At first,the relation between the coefficient of electrode arrangement and the depth of buried electrodes for a four-electrode resistivity monitoring system is given in this paper. Then,the electrical potentials of the layers,in which the source electrode is buried in a three-layer earth model,are presented. Based on the resistivity profile at Baodi station in Tianjin,we have calculated the variation of apparent resistivity with different intervals between two source electrodes and depths of buried electrod... |
