| 摘 要： | 讨论了三原井水位在泾阳4．8级地震前的变化特征，重点是泾阳地震前水位对固体潮响应的变化，即固体潮加卸载响应率与加卸载响应比的变化，对水位观测资料的计算分析表明，震前加卸载响应率及响应比有“平稳－升高－恢复”的特征，说明水位固体潮加卸载响应比方法有可能捕捉5级左右近震的前兆信息。 |
| 关 键 词： | 井水位 固体潮 响应率 加卸载响应比 地震前兆 地应力 |

| Abstract: | the character of groundwater level in Sanyuan well before Jingyang Ms4.8earthquake is discussed,and the emphasis is the variation of tidal response before the event.The analysis on groundwater level indicates that the response ratio of loading and unloading has the feature of smooth-increasing-recovering before the earthquake.The method of response ratio of loading and unloading used in groundwater level tide might catch some precursory information before M5 about earthquakes. |
| Keywords: | groundwater level earth tide response ratio of loading and unloading |
