女山井地下水位潮汐因子初步分析

Preliminary Analysis of Tidal Factor with the Method of Venidikov Harmonic Analysis

利用维尼迪柯夫潮汐调和分析方法和五河县女山井水位2009-2015年原始资料,剔除气压数据影响后,计算出潮汐因子。结果表明,根据原始资料和剔除气压影响后的资料分别计算得到的潮汐因子具有较好的一致性,说明采用维尼迪柯夫潮汐调和分析方法得到的结果基本不受气压因素的影响。同时五河县女山井水位潮汐因子在部分地震前有明显异常表现。

This paper analyzes the tidal factor of the water level data from 2009 to 2015 with or without atmospheric pressure corrections, using the Venidikov Harmonic Analysis Method. The results show that there is a good consistency or correlation between the data with or without the atmospheric correction. And no effects are found on atmospheric pressure by using Venidikov Harmonic Analysis Method. Besides, the results indicate that the tidal factor has obvious abnormal morphologic characteristic.
