摘要

研究表明,地震活动与水位潮汐因子变化有一定的关系,利用地下水静水位对潮汐应力的响应,分析了通河台1号井含水层在一些地震孕育过程中,应力变化的响应形式。运用潮汐计算模型及固体潮汐数字化观测结果,计算了固体潮汐参数,并对其潮汐变化分析出现的异常值进行了系统分析对比,总结了潮汐因子变化异常与地震的对应关系,和该井静水位潮汐变化的映震特征。结果表明,通河台潮汐异常形态对通河台附近的小震活动有较好的对应关系,讨论了通河地震台附近地震活动与水位潮汐因子异常变化的关系。
The research shows that the seismicity is related with the varieties of the water level tidal factors.And based on the response of the tidal stress by the static groundwater level,the stress response forms of the aquiclude of Well I at Tonghe Seismic Station are analyzed during the earthquake preparation.By using the tide computation model and the digital observation data of the solid tide,the abnormal values of the tide variation are compared systematacially.The corresponding relationship between the tidal factor of the variation anomalies and earthquakes is concluded,and also the earthquake reflecting factors of this well’ s static water level.The results show that the tidal anomalies has a better corresponding relationship with the small earthquakes around Tonghe Seismic Station.Lastly,the relationship between the water level tidal factor and the seismicity is discussed.
