| 摘 要： | 2003年4月24日,海原县西安乡上堡子村机井出现了强烈的喷、吸气现象和其它异常现象。经调查落实和分析研究,初步认为:由于此前该地进行了长期大量抽水,造成地下水位下降,形成了裂隙和空洞,在地下水位恢复、气压变化等因素耦合作用下,造成机井出现了水位大幅度升高和喷、吸气等异常现象,排除了是地震前兆异常的可能。

| Abstract: | On April 24, 2003, strong phenomenon of gushing and inhaling gas and other anomalous phenomena of motor-pumped wells occurred in Shangpuzi village, Xi'an country, Haiyuan county. After investigation,analysis and study, the tentative recognition is: long and large amount of pumping water had been done before the anomalous phenomena appeared, and caused underground water level's dropping .And underground cracks and empty holes have appeared. Under the coupling effect of underground water's recovering and atmospheric pressure variation, anomalous phenomena of strong underwater level's rising and gushing and inhaling gas of motor-pumped wells have appeared. This is not earthquake precursory anomaly. |
