Abstract: By using the Yoshimitsu Okada and Steketee fault dislocation model，we calculated the vertical and horizontal displacements along the Yingxiu-Beichuan inverse fault and Guanxian-Anxian inverse fault along which the Wenchuan MS8. 0 earthquake occurred in 2008. Compared to the achievements of field surveying along the surface rupture zone，we found that our computational results are comparable to the real displacement variation trend. Furthermore，the computational results indicated that the surface displacement fields vary with the distance 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 displacement，the horizontal displacement shows relative uniformity in space.
