½éÉÜ£º By using the YoshimitsU Okada and Steketee fault dislocation m odel£¬we calculated the vertical and horizontal displacements along the Yingxiu-Beichuan inverse flault and Guanxian-Anxian inverse fault along which the W enchuan 8£®0 earthquake occurred in 2008£® Compared to the achievem ents of field surveying along the surface rupture zone£¬we found that our com putational results are comparable to the real displacem ent variation trend£® Furthermore¡£the com putational results indicated that the surface displacement fields vary with the dista nee from the fault£¬and the vertical displacement fields show strong inhomogeneity£¬in which larger displacement is focused on the ends of the fault£® However£¬in contrast to the vertical displacem ent£®the horizonta I displacement shows relative uniform ity jn space
