| Abstract: | The sixty eight repeat observations have been done at Jiufeng dynamic geodesy center experiment station using FG5 112 absolute gravimeter in the recent ten years. The standard deviation for each time is less than 2×10 -8 ms -2, and the results show that the environment noise of Jiufeng station is very little and the geologic condition is stable. By the processing and analysis of the observed data, it shows that the increasing rate of gravity at Jiufeng station is about 1×10 -8 ms -2 /a, which corresponds to the vertical displacement rate -0.38 cm/a. Moreover, the influences of groundwater level variation and the like on the result should not be ignored. |
