摘　　要：针对西昌川-03井出现大幅水位下降异常进行了现场核实,调查了该台站自然环境、人为干扰、观测系统,并在现场进行水位校测和人工读数对比观测分析,并综合分析同一台站的其他测项及邻近台站水质的分析结果,分析判定此次水位下降异常是由于台站水位观测系统故障引起,非地震前兆异常。To verify the course of the Xi Chang NO.3 well water level continuity decline,the researchers investigate natural environment,man-made interference factors,observation system inspection of the well,Combining with the water level comparative observation of this well and Chuan NO.32 water level,gas radon and water quality analysis data,we conclude that abnormal phenomenon of water level continuity decline for Chuan NO.03 well was caused by instrument failure,which not belong to precursor anomaly of earthquakes.
