井潮畸变异常信息的提取及应用

METHOD EXTRACTING ANOMALOUS INFORMATION IN EARTH TIDE OF WELL-WATER LEVEL AND ITS APPLICATION

摘要:

本文采用复相关分析方法提取井水位震前的固体潮畸变信息,並给出定量化判别的数值标准,分析中采用日气压系数代替平均气压系数,改正气压对井水位的影响。本文还从映震的角度提出以资料异常率和地震对应率作为水位观测质量的判别标准。最后列举了该方法的实际应用效果。

Abstract:

This paper uses the complex relative analysis method to extract anomalous information in earth tide of well-water level before earthquakes and offers the numerical standard distinguishing the anomalies quantitatively. The daily atmospheric pressure coefficient replaces the mean atmospheric pressure coefficient so as to correct the effect of atmospheric pressure on well-water level. It is suggested that anomalous rate of data and reflective ratio of anomaly to earthquake can be taken as standard distinguishing observed quality of water-level data. Finally, a practical example using this method is cited.
