摘要
针对河北永年地震台水管仪2016年7月21日EW分量快速西倾、NS分量快速北倾的异常现象,进行现场详细调查及排查,发现受7月19日—20日强降雨影响,台站西北方向出现有限范围的雨水汇集区,造成该区域荷载发生迅速变化,利用荷载模型进行定量计算,进一步分析该影响因素对观测结果的影响。
Since July 21, 2016, EW and NS component of the instrument have declined rapidly towards the west and north, respectively. After a detailed investigation and screening on these exceptional conditions of water tube tiltmeter at Yongnian Seismic Station, we found that the heavy rainfall interference from July 19 to 20 lead to a large collection area in the northwest of the station, which resulted in a rapid change in load. In order to further analyzing the abnormal effects, we will make quantitative calculation by using load-model.
