摘要:
基于银川站同址gPhone和GS-15重力仪两年的观测资料,进行潮汐分析和提取重力非潮汐残差处理,从潮汐参数精度、记震能力、抗干扰能力、映震能力等方面进行了对比分析。利用VAV调和分析计算了气压改正前后两台仪器的潮汐参数,发现该站gPhone各波群潮汐参数精度均低于GS-15这一现象,即GS-15运行更为稳定。气压改正后显示GS-15有3种波群潮汐参数变化较大,而gPhone只有S1波较明显。非潮汐残差显示gPhone受抽水影响较GS-15严重,两次地震前有扰动现象。
Abstract:
Based on the two-year observation data of gPhone and GS-15 gravimeter at the same site of Yinchuan Station, the tidal analysis and extraction of gravity non-tidal residuals are carried out, and the comparative analysis is made from the tidal parameters accuracy, the earthquake recording ability, anti-interference ability and earthquake reflection ability. The tidal parameters of the two instruments before and after atmospheric correction are calculated by using VAV harmonic analysis. It is found that the accuracy of tidal parameters of each wave group of gPhone is lower than that of GS-15, that is, GS-15 is more stable. It is also found that the tidal parameters of three wave groups of GS-15 vary greatly after atmospheric correction, while only S1 wave is more obvious in Gphone. The non-tidal residuals show that the gPhone data is more seriously disturbed by pumping than GS-15,and there is disturbance before the two earthquakes.
