摘要
主要用Nakai检验、venedikov调和分析方法对涉县台伸缩仪2010—2017年资料进行分析,结果显示涉县台伸缩仪资料质量较好,北南分量要高于东西分量,两分量的潮汐因子远远大于1;潮汐因子变化可能与应力积累及释放有一定关系,其潮汐因子的异常对地震的发生有较好的预测价值。
The extensometer at Shexian seismic station has been running for 10 years.In this work,we used Nakai and Venedikov harmonic analytical methods to analyze the data obtained by the extensometer over the period of 2010 to 2017.Results demonstrated that the data quality was good.The quality of the south-north component was better than that of east-west component,and the values of the tidal factors of the two components were both far greater than 1.The variation in tidal factors might be related to stress accumulation and release.Thus,the anomaly of tidal factors is valuable for earthquake prediction.
