| 摘 要： | 利用合肥台、黄山台钻孔体应变2013～2015年观测资料日均值与降雨引起的地下水位变化进行相关分析，同时考虑体应变变化的滞后性，使用Matlab计算水位和体应变不同滞后时间的相关系数，确定滞后天数；扣除滞后天数，再进行回归拟合分析，消除水位干扰。鉴于水位对体应变干扰的复杂性，在运用长周期数据时，以月为窗长进行回归分析，能较好地消除水位对体应变的干扰，利于体应变的趋势性判断。

| Abstract: | The interrelation analysis is used in the daily mean values of 2013-2014 bore-hole body strain and underground water from Hefei and Huangshan seismic station. Considering the body strain change lagged the change of water level,this article uses the cross correlation coefficient analysis.Determine the maximum correlation coefficient appeared in the number of days .Through analysis the regression fitting to eliminate underwater interference.The results reflect the real variation of bore-hole to extract seismic anomaly purpose. |
