摘要
山西静乐观测井具有含水层系统对地壳应力—应变响应灵敏的优势,其水位变化对应地震,可间接反映地壳应力—应变特征。2015年7月以来,静乐井水位快速上升,对观测环境、仪器及人为干扰进行分析,并进行同层地下水开采及抽水试验,分析该井水位异常原因,结果发现,降雨量、抽水试验对静乐井水位变化影响不大,而生产用同层地下水开采量减小是该井水位变化的主要原因。
The observation well of Jingle in Shanxi Province has an advantage which aquifer systems are of sensitive response to the crustal stress-strain.The corresponding to the earthquake of Jingle well water level can reflected the crustal stress-strain characteristics.The abnormality cause of the well water level is found through the analysis of the observational environment,equipment,human disturbance and the same layer of groundwater mining and pumping test.The final results indicated that the rapid rise of water level of Jingle well since July 2015 is mainly caused by the reduction of groundwater exploitation in the well from the same aquifer.
