Abstract On the elastic dislocation theory in the homogeniously continuous，isotropic and infinite halfspace, we calculated the coseismic deformation field and gravity field caused by the Wenchuan Ms8.0 earthquake and analyzed the influence of the fault parameters and crustal media structure on the deformation and gravity field. It shows that the calculated results with multisubfaults model are nearly agree with the observed ones and compared to the results with mean dislocation model the accuracy improves to 40%. The effects of layered crustal media model on the horizontal displacement is about 2.7%, the simulation results of layeredmedim earth model are more nearly agree with the observed ones.
