摘　　要：对永安台钻孔体应变观测的干扰特征进行了分析,研究了影响钻孔应变仪观测曲线畸变的一些因素,有助于我们在今后的工作中对TJ-IIC型体应变仪及其他前兆数字化仪器的不同干扰进行识别;同时还总结了观测中碰到的故障情况及解决方法,希望有利于提高台站观测人员对体应变仪的维护经验,提取可靠的观测数据信息,为地震短临预报提供可靠的判定依据和指标。This paper analyzes the interference characteristics of borehole body strain observation at Yong＇an seismic station, and studies some factors affecting the curve distortion of borehole strain meter observation, which is helpful to identify the different interference on the TJ-IIC type body strain meter and other precursory instrument in future work. Meanwhile, the paper also summarizes the fault conditions encountered in the observation and its solution, which is good to improve the body strain meter maintenance experience and extract the observation data for the observatory staff, and provide reliable decision basis and index of short- impending earthquake prediction.
