| Abstract: | In order to get a clear understanding of the cause of reverse of local verti-cal deformation before and after Zhangwu earthquake,repetition measurment data with re-spect to level and gravity in Liaoning province have been processed by means of dynamicdeficit-rank adjustment.According to variation on the map of gravity field,for gravity fieldvariation to have influence on vertical deformation fielol is computed by net method.A mapof vertical deformation field is drawn,which has eliminated the influence of gravity tield vari- ation. |
