| 摘 要： | 分析襄阳万山井数字化水位对苏门答腊M9.0、汶川M8.0和日本M9.0地震的同震效应,结合井台所在地的地质构造背景,总结出井水位同震响应和震后效应等特征.研究结果表明:该井水位同震响应均表现为水位同震下降型阶变,井与井之间的同震效应差别的原因与井所处构造位置、含水层系统的自身特性、地震震级和震中构造位置等有关.

| Abstract: | This paper systematically analyzed the co-seismic and post seismic characteristic from Wanshan well,Xiangyang by Sumtra M9.0,Wenchun M8.0 and Japanese M9.0 earthquake with geological tectonic background.It turns out that the co-seismic effects are the analogous co-seismic groundwater-level changes,because of its structural position,well-aquifer system characteristics,earthquake magnitude,structural position the epicenter,and so on. |

| Keywords: | water level co-seismic step strain structural position earthquake magnitude |
