【Abstract】 During the electrodes buryied beneath the shallow earth surface were supplied with direct current, the electric-field distribution in anisotropic earth crust could be calculated by applying image method and electrostatic analogue method in electromagnetics. Thus the expressions of electric potential and electric-field intensity were obtained.The results could be applied to geologic exploration and detection of riverbank hidden trouble and thus could be served as an effective basis for analysing geologic condition.更多还原
