| Abstract: |
| In this paper, A 3 D elastoplastic damaged constitutive model is established to reflect damage deformation properties of intermittent jointed rockmass according to damage mechanism of jointed rockmass. Through condsidering rock bolt supporting effect for jointed rockmass, we establish a cylindrical damage rock bolt element model to simulate reinforcing effect of anchor bar. Finally, we apply models proposed in this paper to underground power house of XILUODU hydroelectric station to carry out 3 D nonlinear calculation of elastoplastic damage and rock bolt supporting under excavation action and obtain some useful conclusions of project. |
