摘要
选取2015~2016年库尔勒铁门关钻孔体应变资料,经直线拟合,通过小波变换方法中尺度为4的趋势和细节分析。结果表明:提取的趋势和细节曲线形态、周期均发生明显的异常变化,与异常结束后1个月内发生新疆呼图壁M_S6.2地震有关。
Selecting borehole body strain data in Korla Tiemanguan from 2015 to 2016,it took the method of wavelet transform mesoscale for 4 trends and detail analysis with linear fitting. Results showed that extraction of trend and detail curves were obvious abnormal in morphology,period,and after the anomaly Hutubi earthquake with MS6.2 occurred within a month.
