摘　　要：依据观测日志、降雨、水温监测和周边调查,对四川盐源干海双井水位观测干扰事件进行了详细的分类,按分类统计了干海井和干海机井干扰特征,以更加准确有效地识别与排除干扰。针对发生最为频繁的且对正常观测影响最大的堵塞和人为清洗干扰提出了初步技术解决方案。氢氧同位素分析结果表明双井井水受大气降雨补给,可通过收集降雨、河水资料来识别降雨干扰。According to the observation logs,precipitation,temperature monitoring and surrounding investigation,the interference events are classified in detail for the water level observation of the double wells in Ganhai to identify and eliminate interference more accurately and effectively.A preliminary technical solution is proposed for the blockage and man-made cleaning interference that occur most frequently and have the greatest impact on normal observation.The results of hydrogen and oxygen isotope analysis show that the water from two wells is recharged by atmospheric rainfall.Rainfall interference can be identified by collecting rainfall and flow data of river.
