摘　　要：对山东泰安台钻孔应变干扰因素进行了分析总结,结果表明钻孔应变主要受地下水位、气压、系统故障以及电源干扰等影响。持续降雨是影响水位变化的主要因素,分量应变受水位影响较明显。降雪、降雨、大风、气温波动等均会造成气压的剧烈变化。体应变观测曲线与辅助气压曲线呈正相关,与温度变化呈负相关。This article mainly analyzes interference factors of borehole strain observation such as： groundwater level, pressure, system fault and power supply. Continuous rainfall is the main factors affecting groundwater level which influenced component borehole Strain meter. Rainfall, snowfall, gale and temperature fluctuation will cause violent changes of pressure. The observation curve of borehole strain meter positively correlated with pressure and has a negative correlation with temperature.
