Abstract: On the basis of Metis package to decompose domain, this paper combines with row compressed storage mode of large sparse matrix, develops the parallel finite element program according to preconditioned conjugate gradient method for solving finite element equations. Through the calculational simulation to the 3D geological model established, the displacement field simulation result of Zhangdian-Renhe near-fault endangered field indicates that the procedure has a good parallel speedup.
