皖23井水位的强震映震效应

The Strong Earthquake Effection Of Wan23 Well Water Level

地下水作为一种极为活跃的物质,参与了地震的孕育、发生和调整的全过程。而且在地震的前兆显示中起着重要的作用。本研究介绍了皖23井的基本情况,立足于皖23井水位仪对于强震映震现象,根据建立多元线性回归模型,得出了皖23井的强震映震效应与强震震级,震中距的关系,给出了回归方程,并通过检验得出方程显著。该方程表明皖23井对应强震的映震效应跟强震的震级成正比,跟井震距的对数成反比,此种定量分析也有助于我们以后研究皖23井的水位变化及地震异常情况。

As an extremely active substances, the groundwater participates the whole process of the gestation, occurrence and adjustment in the earthquake . Also, water level of the well plays an important role in the earthquake precursory . Based on WAN 23 well water level for the strong earthquake effectien, this paper introduces the basic situation of WAN 23 well, and set up the multiple linear regression model.Then we can found the relationship between the strong earthquake effection and the magnitude,and establish s regression equation to pass the test. This equation shows that the strong earthquake effection of WAN 23 well water level is proportional to the earthquake magnitude,and inversely proportional to logarithmic epicenter distance.Thus quantitative analysis also help us study the change of WAN 23 well water level and seismic anomalies.
