摘要: Some GPS points were set up and occupied and reocupied along the traverse route from Zhongshan Station to Dome-A The result analysis for the GPS data processed by GAMIT/GLOBK package was presented in this paper. It was indicated that the ice along the traverse route flowed with an 8-25 m/a velocity to the northwest in the last three years, which was the direction of the edge of the ice sheet. The maximum horizontal flow velocity is about 100 m/a. Moreover, due to the ice flow, a 0.2-1 m/a sedimentation rate is achieved. Finally, a 1-5 m/a² horizontal acceleration is achieved from the GPS data of the three different stages.
