| 摘 要： | 对天津蓟县地震台2套相对重力仪2018—2019年观测数据进行潮汐分析和提取非潮汐重力残差处理，研究水文变化所引起的重力响应。结果表明，蓟县地震台2套重力仪精度较高；GS-15重力仪重力残差与水文变化间存在较好的相关性，具体表现为降水时重力减少，降水结束后重力增大，水位下降时重力减少，水位上升时重力增大，但其间都存在延迟对应关系。

| Abstract: | Both tidal analysis on the observation data of two sets of relative gravimeters at Tianjin Jixian Seismic Station from the year of 2018 to 2019 and extraction of non-tidal gravitational residual were conducted for studying the gravity response caused by hydrological changes. The results show that the two sets of gravimeters at Jixian Station are of high accuracy and the GS-15 relative gravimeter gravity residual has a good correlation with hydrological changes, which is specifically manifested in the decrease of gravity during precipitation or water level drops and the increase of gravity after precipitation or the water level rises. However, there is a delay correspondence. |
