Based on inversed parameters of Wenchuan MS8.0 earthquake, using the FEM and Static Displacement Analytical Solution Theory, this paper analyzes the influence of the great earthquake on faults in southwestern margin of Ordos block. The numerical result shows that the Wenchuan MS8.0 earthquake, which is the type of thrust with right-lateral component, leads to clockwise disturbance displacement field to the east of the line of Wenchuan-Baoji and anticlockwise disturbance displacement field to the west, which is consist with slide direction of the active faults near the line. The distribution of horizontal shear stress extreme values is consisted with seismicity in the fault zones to the southwest of Ordos block during the year after the great earthquake.
