【摘要】：本文提出了一种地表偶极源干扰影响模型和动态枚举定位求解方法.该方法基于均匀电流场和点源电流场模型,由地表偶极源对不同测点的影响幅度和测点位置求解偶极源位置,并给出了仿真计算结果.利用该方法结合高邮地震台人工干扰源试验观测数据进行计算,计算结果将干扰源定位于30m范围内的小区域,较好地验证了本文模型和定位求解方法的正确性.该研究可为地电观测台站周边工农业漏电干扰源的定位和查找提供有效参考.
[Abstract]:In this paper, a surface dipole source interference model and a dynamic enumeration location method are presented. Based on the model of uniform current field and point source current field, the location of dipole source is solved by the influence of surface dipole source on different measuring points and the position of measuring point. The simulation results are given. This method is combined with the observed data of Gaoyou Seismic Station artificial interference source test. The results show that the interference source is located in a small area in the range of 30 m, which verifies the correctness of the model and the location solution method. This study can provide an effective reference for locating and locating the industrial and agricultural leakage interference sources around the geoelectric observation stations.
