| 摘 要： | 利用2009年1月以来会理川-31井水位及降雨观测数据,定量分析多年来地下水位变化规律与雨季累计降雨量、月降雨量、集中降雨量之间的关系,并依据川-31井水文地质环境特征建立相关的数学物理模型,分析该井降雨量与水位变化幅度的相关性特征;井孔水化学组分及稳定氢氧同位素分析结果表明该井地下水循环深度较浅,补给来源主要为大气降水。该研究结论对地下水位异常判定和和区域震情跟踪工作具有十分重要的意义。

| Abstract: | Based on observation data of the Huili Chuan-31 well water level and local rainfall since Jan.2019,we analyzed the relationship between groundwater level change and rainfall in different periods using the mathematical physics model in consideration of the characteristics of hydrological geology environment.The results of chemical composition and H and O isotopes of groundwater sample indicate that the groundwater in Chuan-31 well circulates in shallow depth originates from the meteoric water.The result of this study may be helpful for seismic monitoring in the future. |
