| Abstract: | Quasi stable adjustment has been carried out to the Three Gorges mobile gravity data since 2010.Six gravity change maps and four gravity change time series curves were obtained.The results show that 1）It is neccessary to test scale value in processing gravity data.2）From 2010，gravity changes curves in Buzhuanghe and Liantuo station are related to water level changes of Changjiang River and its branches.Therefore，the gravity data in the stations should not be used.3）Befores Badong Earthquake，the gravity values rise and fall repeatedly.Badong Earthquake occured in the time when the gravity value was between rising and falling. |
| Keywords: | Three Gorges Badong earthquake water loading gravity changes quasi-stable adjustment |
