降雨量对深井静水位的影响机制分析——以鹤壁井观测数据为例

Analysis of the influence mechanism of rainfall on static water level in deep Wells——Take the observation data of hebi well as an example

我国地震地下水动态观测井水位动态直接受降雨干扰,影响地震前兆信息识别。文章以鹤壁观测井为例,基于2014-2019年鹤壁井静水位观测数据及当地降雨量资料,对鹤壁井静水位主要影响因素及机制进行研究,结果可知:鹤壁观测井的水位相对较浅,静水位受降雨因素影响尤为明显,静水位与降雨量有很强的相关性,变化特性与Gauss-Seidel迭代法一致。在降雨因素对于静水位的影响大于其他因素影响时,影响系数i_n作为未知项,根据i_n和以前的降雨量数据,我们可逆推未来一段时间的水位数据,对评估水位观测井的观测效能及数据异常核实等工作具有指导意义。

The seismic groundwater level dynamic direct dynamic observation,the influence of the rainfall influence earthquake precursor information to identify articles in hebi observation Wells,for example,based on 2014-2019 static water level observation data and local rainfall data of hebi,static level of hebi well to study the main influencing factors and mechanism,result: hebi observation Wells of water is relatively shallow,static level affected by rainfall factors,most notably in static water level and rainfall has a strong correlation,change characteristics consistent with Gauss-Seidel iterative method.When the influence of rainfall factors on the static water level is greater than that of other factors,the influence coefficient inis an unknown term. Based on inand previous rainfall data,we can inversely deduce the water level data for a period of time in the future,which is of guiding significance for the evaluation of the observation efficiency of water level observation Wells and the verification of data anomalies.
