Abstract

The invention proposes a high-space resolution composite electrode cross detection method. The high-space resolution composite electrode cross detection method comprises the following steps of converting vector resistivity of at least two point electrodes, which are not arranged on the same straight line, in a non-Z direction; performing horizontal annular point electrode section detection; performing vertical line point electrode rolling detection; performing multi-layer composite point electrode extension detection; performing space point electrode fixed detection; and performing space resistivity cross conversion, performing interpolation calculation on a space according to composite point electrode cross detection data so as to acquire complete three-dimensional space detection data. By converting the vector resistivity of the at least two point electrodes, which are not arranged on the same straight line, in the non-Z direction, and a complete three-dimensional resistivity dynamicmonitoring method is built by fully combining each detection technology; and by the method, migration law and mechanism of water and salt transport in special soil caused by different disaster chainfactors can be disclosed, and high-resolution and high-accuracy in-situ long-term monitoring on the dynamic change process of water and salt transport space distribution of a coastal zone is achieved.

Description

technical field [0001] The invention belongs to the field of geological detection, and in particular relates to a high spatial resolution composite electrode cross detection method. Background technique [0002] The existing high-resolution resistivity method is a two-dimensional measurement on a survey line. For a target object that is not directly below the survey line, the position and shape of the target object will be inaccurately judged due to the influence of the side effect. When performing area measurement, the measurement lines are simply combined, and there is no inherent connection between the measurement lines. When the general high-density resistivity method is used for three-dimensional exploration, the huge amount of data makes the three-dimensional fitting and inversion time-consuming and difficult to converge. [0003] Based on the above, the invention patent with the application number 200810022181.2 discloses a method named three-dimensional high-resolut...
