| 摘 要： | 衡水冀16井水位2016年经常出现有规律的大幅度异常波动变化，具有小幅下降—持续上升—小幅上升—持续下降变化形态，日变最大幅度0.73 m。通过现场核实，发现观测仪器工作正常，附近鱼场地下水开采量增加。增加辅助观测仪器同井对比水位观测，并对鱼场2口冷水井进行抽水试验，分析衡水冀16井水位异常变化原因。结果显示，衡水冀16井水位大幅波动异常变化可能因冷水井1抽水所致，冷水井2无影响。

| Abstract: | In 2016, the water-level of Hebei Hengshui No.16 well often abnormally changes regularly in a large range, with a pattern as slightly decreasing, then continuously increasing. and slightly increasing, followed by continuously decreasing. Its daily change amplitude is 0.73 m in maximum. Through the field verification, it is found that the instrument works well and the amount of groundwater exploitation in the fishing farm around the well observation station increased. By carrying out the test of pumping water from the two cold wells locating at fishing farm and adding comparative observation of water level at auxiliary well, we analyze the reason of the abnormal change of the water level at Hebei Hengshui No.16 well. The result reveals that pumping water from the No.1 cold well at fishing farm affects greatly on the abnormal change in a large scale of the water-level of Hengshui No.16 well in Hebei, and the No.2 cold well at fishing farm has no effect. |
