Abstract: The effect of earth tide on water level in seven wells of the Ningxia well network is systematically studied.Tide parameters of main tide wave effecting on the water level in seven wells are given after harmonic analysis.From the tide parameters some physico-mechanical parameters of aquifer in seven wells are obtained.The ability of well-aquifer system to reflect the crustal stress and strain and using the effect of tide on well water level to study earthquake prediction are discussed.

Key words: Ground water level, Ningxia, Earth tide, Earthquake prediction

摘要： 系统研究了宁夏地震地下水观测井网中7口国家井的井水位固体潮效应。对7口井的观测资料进行了调和分析,给出了各井孔井水位固体潮主要潮汐波的潮汐参数。利用湖汐参数计算了各井孔含水层的某些物理力学参数,并对各井孔井-含水层系统探测地壳内应力应变状态的能力及利用井孔潮汐效应进行地震预报等问题进行了探讨。
