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.
This paper proposes a surface dipole interference model and a location method by dynamic enumeration.This location method adopts interference amplitude and location of different measuring electrodes to calculate location of the dipole source based on a uniform current field and apoint source model.And then some simulation results are also presented.Furthermore,taking the test data of artificial interference sources experiment in Gaoyou seismic station as an example,the interference sources are located within 30 meters by this method,verifying the validity and feasibility of the model and the algorithm.The present research will provide an effective method for locating the leakage interference sources around geo-electric observation stations.
