摘要
对北杜井水位异常动态变化特征进行了分析研究,表明在张北6.2级地震前,水位有"上升—下降—地震"的异常现象。利用"十五"攻关刘喜兰等改进的从属函数方法进行计算,也表明水位有从属函数异常,在异常开始后第9个月发生张北地震。无论是定性分析、还是定量计算,都显示张北地震前北杜井水位有明显的中期异常变化,说明北杜井水位对华北地区发生的强震有一定监视能力。
The research to the variation of groundwater level in Beidu well shows that there was a rising-descending anomaly in the water level before Zhangbei Ms6.2 earthquake. Processed with secondary function, the data is also showed an anomaly. Zhangbei earthquake happened 9 months after the appearance of the anomaly. Thus we concluded that the well has some monitoring capacity for the earthquakes in North China.
