The invention relates to a method and system for positioning a dipole interference source in earthquake geoelectric observation, wherein the method comprises the following steps of: taking a leakage interference source as a ground surface dipole source, and establishing an influence model of the ground surface dipole source on the geoelectric observation; measuring the potential generated by the ground surface dipole source at different measuring points; calculating the position coordinate of the ground surface dipole source according to the potential difference between any two measuring points. According to the technical scheme, the leakage interference source is taken as the ground surface dipole source, the influence model of the ground surface dipole source on the geoelectric observation is established, the potential generated by the ground surface dipole source at different measuring points is measured, and the position coordinate of the ground surface dipole source are calculatedaccording to the potential difference between any two measuring points, so that the consumed manpower and material resources of the prior interference source investigation can be greatly reduced, therapid and accurate positioning can be achieved, the interference source is limited in a small area range, and the problems of long time consumption, low efficiency and low accuracy for positioning the leakage interference source in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of seismic geoelectric observation, in particular to a method and system for locating dipole interference sources in seismic geoelectric observation. Background technique [0002] With the development of my country's urbanization, the situation of industrial and agricultural electricity consumption around the seismic geoelectric observation stations is becoming more and more complicated, and the leakage of electricity from industrial and agricultural electricity around the stations will interfere with geoelectric observations. This interference signal Superimposed on the normal changes in the geoelectric field, it will cause a large disturbance in the observation data. In severe cases, it will also lead to the distortion of the daily variation of the geoelectric field observation, and the increase in the variance of the georesistivity observation, which will affect the quality and application efficiency of the...
