摘要
本文简单介绍了中国地下水潮汐的观测研究情况,介绍了对承压水位潮汐机理研究的理论结果,给出了固体潮体应变、气压和海洋潮汐对承压水头影响的偏微分方程,从这些方程的简化解讨论了它们与含水层参数间的关系.并从全国选取了33口有代表性的井孔,对这些井孔的水位和气压观测资料采取反复调和分析的方法,求出了它们的水位固体潮体应变各分波的潮汐系数和位相滞后,也求出了水位气压各分波的系数和位相滞后.
In this paper the situation of the observation and research of underground water tide in China and the result of theoretical study of the tidal mechanism of water level of a confined aquifer are introduced briefly. The partial differential equations of the influence of bulk strain due to earth tide,barometric pressure and oceanic tide on the water head in confined aquifer are given. The relations between the influence and the parameters of the aquifer are discussed according to the simplified solutions of the equations. In addition,the tidal coefficients and the phase lag of each tidal component of bulk strain due to earth tide for the water level at thirty-three representative wells chosen from China are calculated repeatedly by the method of harmonic analysis. The barometric coefficients of water level and the phase lag are also calculated.
