| 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。 |
| 关 键 词： | 地下水位 体应变 固体潮 含水层 潮汐因子 同震响应 |

| Abstract: | This paper inverted body strain of aquifer caused by Wenchuan earthquake with MS8.0 and 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 aq-uifer caused by earthquakes was 10 -8 magnitude while strain of Yongchun well was about 10 -7 mag-nitude. |
| Keywords: | Groundwater Body strain Tide Aquifer Tidal factor Co-seismic respond |
