摘要
内蒙古通辽库伦CK3井水位、水温自2015年以来每年4月至11月份均会出现大幅度下降变化。为核实该异常性质,确定是否为地震前兆异常,笔者在研究井区的地质构造及水文地质特征的基础上开展了一系列调查分析工作。结果表明,库伦CK3井水位、水温低值异常变化主要受周边地下水开采影响导致,非地震前兆异常。分析发现,因对水位、水温造成影响的抽水井较多,影响程度差异较大,因此建议从根源上采取措施,严格按照相关规范选址重建或改变该井的观测系统。
Since 2015, the water level and water temperature of Kulun CK3 Well have significantly decreased from April to November every year. On the basis of studying geological and hydrogeological characteristics of well area, a series of abnormal verification work has been carried out. The results show that, the anomalies of well water level and low water temperature are non-precursory anomalies which are affected by the surrounding groundwater exploitation. It is suggested to relocate the site and build a new professional seismic observation well in strict accordance with the relevant regulations.
