【摘要】 针对安庆皖23井水位2017年1月1日以来出现破年变异常现象,经现场调查与水位校测,发现环境干扰较小,观测数据变化真实可靠;通过井水位与降雨量相关性分析,认为其与降雨量关系不大;水化学离子平衡与氢氧同位素分析结果表明,其与附近石塘湖具有不同的物质来源,安庆皖23井存在外源输入影响;水位固体潮调和分析及以往震例表明,本次异常可能包含了地震构造活动信息,对其周边中等以上地震危险性有一定指示意义。更多还原

【Abstract】 The water level in Anqing No.23 Well is broken annual variation since Jan. 1,2017. Field investigation reveals that there is little interference in the circumstances and the water level variation is relatively reliable. Through the correlation analysis of No.23 well water level and rainfall, it is concluded that it has little relationship with rainfall. The results of hydrochemical ion equilibrium and hydrogen and oxygen isotope analysis show that it has different material sources from the nearby Shitang Lake. The analysis of earth tide harmonic of water level and previous earthquake examples show that this anomaly may contain information of seismic tectonic activity, and it has certain indicating significance for the earthquake hazard in the surrounding area.更多还原
