| Abstract: | 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 regularity for underground water level dropping large scale in groundwater overdraft area,which provides scientific reference for identifying earthquake anomalies. |
