信阳台伸缩仪降雨干扰特征分析
|
摘要
利用2013～2016年信阳台伸缩仪观测资料和降雨资料,对每次降雨后伸缩仪的变化进行分析,利用M2波潮汐因子分析仪器格值的变化情况,并对观测资料进行格值归化。最后得到信阳台伸缩仪和降雨之间的回归关系,对排除降雨干扰、识别异常有借鉴作用。
We analyze the regression relation between the extensometer observation data from 2013to2016 and the cumulative precipitation.By calculating the M2 tide factor,we modify the extensometer observation during the rainfall,which plays an important role in eliminating rainfall disturbance anomalies.
