摘　　要：陇县八渡形变台水管倾斜仪东西分量自2021年8月开始发生趋势转折,加速明显,至2021年12月水管仪东西分量再次发生反向快速转折。针对此项异常变化,宝鸡中心站对观测系统、洞室站周边环境、气象、水文地质等因素进行了异常核实,并对各项干扰因素进行了综合分析。分析结果认为,八渡形变台水管仪东西分量此次快速趋势转折变化为人员进洞调零和降雨事件叠加所致,为人为干扰及气象干扰异常。The EW component of water pipe tiltmeter of Longxian Badu deformation station began to turn the trend and sped up obvious from August 2021.By December 2021,the EW component of the water pipe instrument had a reverse rapid turning point again.In response to this abnormal change,Baoji Central Station carried out anomaly verification about observation System,surrounding environment of Cave and station,meteorology,hydrogeology and any other factors,and made a comprehensive analysis of the interference factors.The results show that this rapid trend turning change of EW component of the water tube tiltmeter at Badu deformation station was caused by the superposition of the personnel entering the tunnel and the rainfall event,which was the anomaly of human interference and meteorological.Correct anomaly identification of interference and earthquake precursor has important significance for observation data application.
