| 摘 要： | 本文对北京市昌平地震台东三旗井数字化水位观测中出现的锯齿型“凹型”阶变现象进行了研究，并结合观测环境条件、同井孔体应变观测、区域地震活动、GPS地面沉降观测等分析，探析了该异常现象的成因。结果显示，该变化可能与环境变化引起区域周围电磁场的改变有关，可能是地震活动或应力应变引起电磁量增加导致水位仪器电信号干扰异常引起，是前兆异常特征的可信度低。

| Abstract: | This paper studied the zigzag concave shape of the digitized water well,and analyzed the reasons for the anomalies,in terms of environmental conditions of the observatory,volume strain observation in the same well,regional earthquake activities and GPS land subsidence observation in Dongsanqi well.The result shows that the change may be related to electromagnetic magnetic field changed,induced by environmental change,earthquake activity or stress-strain change may cause electromagnetic the anomaly,But it showed low reliability as precursor abnormalies. |
