在系统分析山东钻孔体应变与辅助观测资料的基础上,结合台站工作日志对引起钻孔体应变观测曲线出现波动性短时异常变化的干扰因素进行了分析讨论,结果表明:钻孔体应变的短时波动性变化主要为气压、降雨、地下水位、施工和电源等的干扰影响;这些干扰影响不能通过相关分析完全剔除,需定量与具体情况定性相结合分析;气压、降雨和地下水位的影响程度与钻孔地质条件密切相关,有破碎带的钻孔受干扰影响相对较大。
Based on the systematic analysis of the data of the strain and the auxiliary observation of Shandong drilling bodies, the disturbance factors that caused the short-term fluctuation of the short-term fluctuation of the observation curve of the borehole body were analyzed and discussed in combination with the station logbook. The results show that: The short-term fluctuations of strain are mainly caused by the interference of air pressure, rainfall, groundwater level, construction and power supply, etc. These interference effects can not be completely eliminated by correlation analysis, and the combination of quantitative analysis and qualitative analysis is required. The atmospheric pressure, rainfall and groundwater level The degree of influence is closely related to the geological conditions of drilling. The borehole with broken belt is relatively affected by the interference.
