【摘要】 分析了汶川地震前后周至台流体数据异常特征,特别对该台水位、流量数字化资料分钟值的的毛刺现象进行了深入研究,并用水位的整点值做了潮汐变化分析和小波分析。结果表明,汶川地震前,该台流体观测有一定的前兆显示,为流体学科的异常判定提出了新的思路。更多还原

【Abstract】 This paper analyses the anomaly characteristics of fluid observation data in Zhouzhi deep borehole pre and post Wenchuan earthquake,especially makes a deep study of the burr phenomena of water level and flow with digital minute value data,and using wavelet analyses the tidal variation with water level integral point value.The results show that there are some precursors before Wenchuan earthquake in fluid observation in the borehole,which provides a new method to subsurface fluid precursor’s anomaly judgment.更多还原
