摘要

使用FG5绝对重力仪对中国大陆构造环境监测网络12个近海基准站进行了绝对重力的测定,结果表明:组间标准差均优于5×10-8ms-2。同时还分析了固体潮和海洋负荷对测定结果的影响,以及FG5绝对重力仪对日本Ms6.0地震的同震响应。
The FG5 absolute gravimeter was applied to the absolute gravity measurement at the 12 absolute gravity fiducial stations of the Crustal Movement Observation Network of China near the ocean.The Earth tide and ocean loading correction were analyzed in the absolute gravity determination.As a result,the FG5 absolute gravimeter at Shanghai fiducial station precisely detected the coseismic response to Japan Ms6.0 earthquake.The standard deviation of Set Scatter of all stations was proved to be better than 5×10-8ms-2.
