Abstract: A 3 D elastoplastic damage constitutive model and a cylindrical rock bolt element model are proposed in this paper. The proposed models have been applied to the stability analysis of Xiluodu underground power house under construction. The 3 D non linear FEM analysis of surrounding rockmass gives satisfactory results.
