宁夏固原东山坡井水位异常分析

Analysis of Water Level Anomaly in Dongshanpo Well, Guyuan, Ningxia

摘要: 文章通过井点背景资料、观测系统检查、水温梯度实验、地下水类型定量诊断分析、井水位频谱分析、同位素与水化学组分分析、地下水运移及影响因素分析、含水层参数计算、降雨荷载影响因素分析、区域应力背景分析等方法，对宁夏固原东山坡井水位2024年7月22日出现的快速上升变化异常进行分析论证。结果显示，此次异常与2024年7月中旬当地出现的集中、雨量充沛的降雨活动有关，综合确认为干扰异常，而非地震前兆异常。

Abstract: This study investigates the rapid water level rise anomaly observed at the Dongshanpo Well in Guyuan, Ningxia, on July 22, 2024, through multiple analytical approaches. These include: Background well data review, Observation system inspection, Water temperature gradient experiments, Quantitative diagnostic analysis of groundwater types, Well water level spectral analysis, Isotope and hydrochemical composition analysis, Groundwater migration and influencing factor analysis, Aquifer parameter calculation, Rainfall loading impact analysis, Regional stress background analysis. The results demonstrate that the anomaly is associated with intensive and abundant rainfall events concentrated in mid-July 2024 in the local area. Comprehensive analysis confirms this event as an interference anomaly, rather than a seismic precursor anomaly.
