【摘要】 在对福建地区井水位固体潮M2波海潮负荷改正的基础上,尝试反演汶川MS8.0、日本MW9.0地震对福建地块的井-含水层系统产生的体应变变化。为此收集了汶川、日本大地震时该地区的地下井水位资料,挑选出同震响应明显的井水位资料,计算出各井孔的井水位潮汐因子,从而反演出福建地块井-含水层系统受到的同震体应变变化。结果表明,地震对各井孔所处的含水层造成的体应变基本在10-8量级上,而2次地震对永春井产生的体应变均为10-7量级。更多还原

【Abstract】 This paper inverted body strain of aquifer caused by Wenchuan earthquake with MS8. 0and Japan earthquake with MW9. 0 through correction for tidal factor. They calculated tidal factor to inverted co-seismic strain of aquifer using water level data in Fujian. The results showed strain of aquifer caused by earthquakes was 10-8magnitude while strain of Yongchun well was about 10-7magnitude.更多还原
