摘要:
通过研究1990—2019年云南普洱大寨井水位的同震响应特征,分析井水位响应特征的变化与后续中强地震的关系,并探讨含水层渗透性对区域构造活动的影响。结果显示:当同震响应幅度偏离统计关系时,井孔周边区域后续地震活动有所增强; 固体潮相位差由负值变为正值,表明观测井孔含水层渗透性参数发生改变,这与区域地震活动的变化可能存在一定的相关性。分析认为,井水位同震响应和含水层渗透性参数变化可作为探索区域构造和地震活动的参考指标。
Abstract:
In this paper,we studied the commonalities and differences of the co-seismic responses recorded in the water level of the Pu’er well,analyzed the relationship between the change in the earthquake recording ability of the observation well and the subsequent earthquakes,and discussed the response of the aquifer permeability to regional tectonic activity.The results show that,when there were some significant differences in co-seismic response amplitude from the statistical relationship and the maximum amplitude of the waveform,there was a certain correlation with subsequent seismicity in the area.The phase-lag changed from negative to positive,while the permeability of the observation wellbore aquifer changed,which also had certain correlation with the seismicity or other fluid observations in the area.It showes that the changes in co-seismic response and aquifer permeability can be used as parameters for judging regional structure and seismic activity.
