摘要
选取河北省昌黎、阳原、大柏舍、兴济、肥乡、滦县6个地震台站地电场观测资料,通过资料整理、日志查阅、干扰源调研,对常见观测系统故障、工频干扰、雷电干扰、高压直流输电、地电暴等干扰源的表现形态及干扰机制进行分析,并提出干扰排除方法,为有效识别干扰、异常提取及地震预测预报提供可靠依据。
By sorting out the observation data of geoelectric field at Changli, Yangyuan, Dabaishe, Xingji, Feixiang and Luanxian seismic stations in Hebei Province, through processing of data, log query, and investigating the interference source, we summarize the forms of various interference sources and interference mechanism such as line fault, power line interference, lightning disturbance, hvdc, and geoelectric storm in the observation of geoelectric field and then put forward the method for eliminating the interference. It provides the reliable basis for effectively distinguishing the interference of the geoelectric field, extracting anomalies and predicting earthquakes.
