【摘要】 利用GAMIT/GLOBK软件,处理IGS跟踪站观测数据,得到2011年3月11日的日本9.0级地震期间的地表变形序列。首先采用GAMIT/GLOBK软件得到GPS测站震前和震后的单天解坐标;然后采用TRACK模块得到GPS测站的震时三维坐标时间序列动态变化。通过对GPS测站坐标序列进行分析和比较,揭示了GPS测站的震时地表三维形变过程和震后地表永久性形变。更多还原

【Abstract】 By using GAMIT/GLOBK software,the coseismic surface movement information is extracted from IGS stations data located in Japan.Firstly,using GAMIT/GLOBK,this paper obtained the pre-seismic and postseismic three dimensional coordinate in 24 hours solution of GPS sites.Then,the coseismic three dimensional coordinate time series is achieved using Track model.Based on the GPS coordinate time series,it reveals the coseismic surface movement process and post-seismic permanent deformation of GPS sites.更多还原
