摘要

以洛阳地震台地电数字化观测资料为基础,阐述了地电场数据测量原理及其在分析中的应用,并通过对地电暴、避雷装置和电极故障3个地电场数据异常案例研究分析,得出当出现故障时应该遵循"替换法"和"逐步逼近法"原则。
In this paper,the principle of geoelectric field measuring and applications are expounded based on the analysis of geoelectric digitized observation data of Luoyang Seismic Station.By case analysis on anomalous data produced while the electric storm,lightning protection and electrode failure,It is found that,when malfunction is appearing,we should follow the principle of replacement and progressive approach,adopting anomalous elimination method that is indoor to outdoor,first device,instrument,again after outside line,then the observing environment and observation field,finally electrode.And so we can improve processing ability to digitized observation interference data,as well as strengthen the ability for right analysis and estimate the dynamic changes of underground medium.
