摘　　要：选取2015-2022年富蕴台CZB-2A型竖直摆钻孔倾斜仪观测数据,分析总结了钻孔倾斜仪器运行情况、观测系统、观测环境、人为干扰等干扰因素,特别是每年春季冰雪消融导致速率转向畸变等,其变化幅度和速率与积雪量成正比,并对观测数据异常特征进行了分析。结果表明,蒙古M S5.9地震前倾斜速率、潮汐因子异常明显,说明富蕴竖直摆钻孔倾斜仪具有一定的地震前兆异常监测能力。Observation data of CZB-2A vertical pendulum borehole tiltmeter at Fuyun station from 2015 to 2022 were selected,and the interference factors such as the operation of borehole tiltmeter,observation system,observation environment and human disturbance were analyzed and summarized,especially the rate steering distortion caused by ice and snow melting in spring every year.The change range and rate are proportional to the amount of snow,and the abnormal characteristics of observation data are analyzed.The results show that the tilt rate and tidal factor anomalies before Mongolia M_(S)5.9 earthquake are obvious,indicating that the Fuyun vertical pendulum borehole tiltmeter has a certain ability to monitor earthquake precursor anomalies.
