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三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,采用“由室内向室外、先装置、后仪器、再外线路、接着观测环境和观测场、最后电极”的异常排除方法,提高了地电观测人员对数字化观测干扰数据的处理能力,及对地下介质的动态变化做出正确分析、判断的能力。
This paper expounds the principle of geoelectric field measuring and applications in analysis according to Luoyang seismic station of geoelectric digitized observation data. By case analysis while the electric storm, lightning protection and electrode failure produce anomalous data, 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 improve processing ability to digitized observation interference data, however, strengthen right analysis and estimate of ability to underground medium of dynamic change.
