摘　　要：通过研究河北平原区地下水超采区第四系第三承压含水层水位的变化机理,依据上覆地层的荷载效应、非稳定流抽水中弱透水层的释水和越流过程,阐明地下水超采区内地下水位大幅下降的内在规律,为科学合理地提取地震前兆信息提供科学依据。This paper analyzes the change mechanism of water level in the quaternary system the third confined water- bearing stratum in groundwater overdraft area of Hebei plain. Based on the load effect of overlying strata and the release and over-flow process of pumping in the soft-filter stratum of non-steady flow, it illustrates internal regu- larity for underground water level dropping large scale in groundwater overdraft area, which provides scientific reference for identifying earthquake anomalies.
