| 摘 要： | 对安置于十三陵地震台的两台gPhone重力仪(109、118号)在2013-04~08的连续观测数据进行潮汐分析和提取重力残差处理。结果表明,gPhone重力仪监测到降水导致μGal量级的重力变化;gPhone重力仪获取的二阶重力残差变化与距离十三陵地震台15km的沙河地震台静水位变化之间存在4d左右延迟的正相关对应关系,显示了地下水位观测对重力观测解释的必要性。因此,有必要对我国的连续重力观测网补充地下水位观测,提高连续重力观测的数据处理精度。

| Abstract: | We did tidal analysis and extracted gravity residual from continuous gravity records of gPhone meters (serial number 109 and 118) at Shisanling seismic station from April to August in 2013. The results showed the gPhone meters successfully detected the gravity variations at μGal level, which are caused by rainfall| the delay time of positive correlation between the 2nd-order curve fitting residual gravity of gPhone data and the static water level of Shahe seismic station (15 km from Shisanling seismic station) is about 4 d. Such a positive correlation indicates that the hydrology records are very important in the explanation of the observed gravity data. Therefore, to increase the processing accuracy of gravity data, it is necessary to add groundwater level observations to the continuous gravity observation network of our country. |
