摘要
对洛阳地震台2018—2020年地电场观测资料进行汇总分析,归纳出测区因漏电造成的观测系统的异常记录;通过近场地人工供电模拟漏电干扰,观察在测区周边正反向供电和不同电压供电时观测系统和漏电检查仪的对比变化,与观测系统漏电异常记录进行对比分析,探讨近场地漏电对洛阳台地电场的影响,得到数据干扰异常阶跃方向及幅度变化,为数据干扰及异常核实提供理论参考依据。
Based on the summary and analysis of the geoelectric field observation data of Luoyang Seismic Station from 2018 to 2020,the abnormal records of the observation system caused by electric leakage in the survey area are summarized.Through the artificial power supply near the site to simulate the leakage interference,the comparative changes of the observation system and the leakage detector under the forward and reverse power supply and different voltage power supply around the survey area were observed.Comparing and analyzing with the leakage anomaly records of the observation system,the impact of near-site leakage on the geoelectric field of Luoyang Seismic Station is discussed,and the step direction and amplitude changes of abnormal data interference are obtained,so as to provide a theoretical reference for data interference and anomaly verification.
