以汶川 MS 8.0地震、日本 MW 9.0地震和尼泊尔 MS 8.1地震为例,统计了天津地区7口井水位的同震响应特征。在此基础上,利用水位反演含水层体应变的方法,反演出天津地区井含水层的同震响应体应变变化量。结果表明,利用水位同震变化量反演出的含水层体应变,能够较为真实地反映出井孔所在位置的应变变化情况。
Taking WenchuanMS8 .0 ,Japan MW9 .0 ,Nepal MS8 .1 as instances ,this paper analyzed the co‐seismic response characteristics of 7 wells’ groundwater level in Tianjin .On this basis ,we inversed the volumetric strain of this 7 wells’ aquifer .The results show that ,the variations of the volumetric strain of aquifer inversing by groundwater level with earthquake can realistically reflected the strain variation of the location borehole .
