厦门天马井LN-3型水位观测仪记震分析

摘要

The water level observation curve,which Tianma well LN-3-type water level observations recorded,shows： first.in Xiamen,for a closed water layer,rainfall is the most serious impact on the groundwater level.To eliminate the impact of rainfall on groundwater,the regression analysis was used to analysis the data,regression analysis;curve reflected the change in groundwater level after the earthquake.second.Recorded water borehole seismic images show the same response in the same way on the fault line;if the magnitude decreases,the corresponding rate is also reduced.%通过对天马井LN-3型水位观测仪记录的水位观测曲线进行分析,结果显示：1.在厦门地区,对一个封闭水层而言,水位的变动以降雨量的影响最为严重,可以用回归分析方法从观测数据中消除降雨影响,使加工后数据更好地体现地震影响。2.通过记录到的水震波图像,可以得出同一井孔对同一断层上的响应方式是一致的,只是对震级大的地震响应幅度大,震级减小,相应幅度亦减小。大震产生的水位波形震荡时间长衰减慢。
