摘　　要：通过对近几年兴济地震台地电场电极故障判断及更换工作进行总结,得出通过数据图像同步变化特征判断电极故障的方法;在更换电极时,较好的更换方法可以增强电极使用性能,延长电极使用寿命。如,使用洛阳铲挖取电极坑,减少对原土层的破坏;埋设电极尽量在潜水层水面以下,保障电极使用环境稳定;电极埋设后等一周时间,待电极稳定后再接入观测等。该经验总结可为及时判断电极故障以及优化电极更换方法提供借鉴参考。Based on the summary of the geoelectric field electrode fault judgment and replacement work of Xingji seismic station in recent years,the method to judge the electrode fault through the synchronous change characteristics of data image is obtained.When replacing the electrode,the better replacement method can increase the electrode performance and prolong the electrode service life.For example,the Luoyang shovel can be used to dig the electrode pit to reduce the damage to the original soil layer;the electrode should be buried as far as possible below the water surface of the phreatic layer to ensure the stable use environment of the electrode;after the electrode is buried,a week should be waited for the electrode to be stable before the observation.The experience can be used for reference in judging electrode fault and optimizing electrode replacement methods.
