临汾台洞体形变典型干扰与地震异常图像识别

Recognition of Typical Disturbance of Cave Deformation and Seismic Anomaly Image in Linfen Station

文章分析了临汾台水平摆、垂直摆两套洞体形变观测仪记录曲线的正常变化形态,讨论了人为和自然因素引起干扰的图像特征,以及山西带南部3次中等地震前典型异常图像特征,分析结果为今后观测数据处理、异常识别及异常跟踪分析判定提供参考。

This paper analyses the normal variation patterns of the horizontal pendulum and vertical pendulum observation curves at Linfen Station,and discusses the image characteristics of disturbance caused by man-made and natural factors,and the typical anomaly image characteristics before three moderate earthquakes in the south of Shanxi seismic belt.These observation results will have positive reference value for future observation data processing,anomaly identification and anomaly tracking analysis and determination.
