摘要
利用2012—2016年江苏省南京市高淳台钻孔应变观测数据出现的8次突变(阶跃)事件,通过对其突变形态特征、阶跃幅度、持续时间及异常性质进行分析,并结合地震实例探讨钻孔应变与地震前兆异常机理之间的关系。
Based on the eight sudden jumps （abrupt） of the YRY-4 drilling strain data of Gaochun seismic station in Nanjing city, Jiangsu Province from 2012 to 2016, the abrupt characteristics, abnormal amplitude, duration and abnormal properties were analyzed. The relationship between the borehole strain and the earthquake anomaly mechanism is discussed.
