Analysis of Imformation of Vertical Deformation of Xian-Shui River Multi-Seismic Region

In this paper,to build the method of the vertical deformation model in the multiseismic region is emphatically discussed.The method considers that the earthquake effect on deformation of the surface points,especially,those points near the seismic center may be make a sudden change displacement at the earthquake.By means of analysis of practical levelling network,some of the proposals about the design of the vertical deformation network and the analysis of observed data are proposed.
