| 摘 要： | 通过对通河地震台地电场观测资料的分析判断,利用本台站地电场观测同时段不同测项、附近地电场观测台站地电场观测同时段相同测项对比分析,排查影响本台站地电场观测干扰源,识别干扰形态并进行分析。结果表明,在地电场观测过程中存在可控的干扰源有:人为抽水干扰、工厂运行干扰、农田灌溉干扰等;不可控的干扰源有:雷电干扰、高压直流输电干扰、地电暴干扰等。通过对观测数据干扰形态的识别与排除,对提高地电场数据质量有一定的意义。

| Abstract: | Through the analysis and judgment of the observation data of the geoelectric field at Tonghe Seismic Station,different items of geoelectric field observation in the same period at our station,and the comparative analysis of the same items in the same period of geoelectric field observation at nearby geoelectric field observation stations,the interference sources affecting the observation of geoelectric field at this station are investigated,and the interference forms are identified and analyzed.The results show that there are controllable interference sources in the process of geoelectric field observation,such as artificial pumping interference,plant operation interference,farmland irrigation interference,etc.The uncontrollable interference sources include lightning interference,HVDC transmission interference and ground electric storm interference.By identifying and eliminating the disturbance form of observation data,it has certain significance to improve the quality of geoelectric field data. |
