Abstract: Miero fluctuations related to the stress-strain change in rocks holding water are studied by use of such method,other than the dynamical approach,as the Pertsev's filter to resolving long/short-term variations of water level and regression analysis to eliminating and analyzing the correlation factors affecting the water level.The compromise analysis is applied to the analysis of earth tide of water level.The multichannel welner filtering is used for comprehensive predicting the fluctuations of ground water level and searching out the abnormal time-interval prior to an earthquake.At last,the observed data of water level from the well at Ta-Yuan in Beijing are of practical significance in providing the information about seismic indications and in distinguishing anomalies in water level from the normal fluctuations.

摘要： 地下水位动态是各种因素综合作用的结果。研究含水岩体应力-应变造成的地下水动态(即微动态),不能单纯用地下水动力学方法进行分析,我们从其他学科引入一些方法,试图解决这个问题。当分离水位趋势变化和短周期变化时,用别尔采夫滤波方法;当分析并排除影响水位动态的相关因素时,用回归分析方法;分析水位固体潮的若干潮波时,用调和分析方法;综合预测水位动态,寻找异常时段时,用多道维纳滤波方法。最后,通过北京塔院井水位观测的具体震例,来说明资料处理对了解水位的正常动态、异常动态,提取地震前兆信息有实用意义。
