【摘要】 对福州地震台TJ-2型钻孔体应变观测资料进行整理,识别并统计引起数据曲线发生畸变的干扰因素,认为主要有气压、降雨、地下水、雷电、电源干扰等因素。分析各影响因素干扰特征,以便识别体应变观测资料干扰异常。更多还原

【Abstract】 Since the observational data of borehole strain was finished of TJ-2 observation at Fuzhou Seismic Station,the interference caused by data curve distortion was analyzed for identification and classification of statistics. It shows that the factors causing Fuzhou borehole strain data curve distortion are pressure,rainfall,groundwater,lightning and power disturbance. This work will be useful for staff to identify interference and to improve data utilization rate.更多还原
