摘　　要：通过系统全面地整理、分析北武当观测站2012—2019年水平摆、水管仪、伸缩仪观测资料,总结形变资料时序图曲线突跳、台阶、趋势上升、趋势下降、抖动等特征,运用潮汐因子变化分析、加卸载响应比分析2种地震前兆数据处理方法对形变资料进行分析。结果表明,对于不同震级地震而言,地震发生前异常显现时间的长短和变化有所不同,但是地震与异常并非一一对应。因此可以将研究方法及结果推广到其他地震前兆监测数据的干扰分析以及年度地震趋势预测研究工作中,用于地震前兆观测资料年变趋势对比分析,以寻找长期异常变化。By systematically and comprehensively sorting out and analyzing the observation data of horizontal pendulum,plumbing instrument and extensometer in North Wudang observation station from 2012 to 2019, summarize the characteristics of sudden jump, step, trend rise, trend decline, jitter and other characteristics of the time series diagram of deformation data,and analyze the deformation data using two kinds of earthquake precursor data processing methods, namely, tidal factor change analysis and load-unload response ratio analysis. The results show that for earthquakes of different magnitudes, the length and change of anomaly appearance time before the earthquake are different, but the earthquake and anomaly are not one-to-one corresponding. Therefore, the research methods and results can be extended to the interference analysis of other earthquake precursor monitoring data and the annual earthquake trend prediction research, which can be used for the comparative analysis of the annual variation trend of earthquake precursor observation data to find long-term abnormal changes.
