    CONSTITUTIVE MODEL FOR ENERGY DAMAGE OF JOINTED ROCKMASS AND ITS ENGINEERING APPLICATION

    • According to the Bettis reciprocal energy theorem, energy damage evolution equation of jointed rockmass, generalized normal flow rule, and consistent condition of plastic damage, A 3 D constitutive model for energy damage of jointed rockmass is firstly constructed in this paper. Then a 3 D Nonlinear FEM Computation program about the constitutive model has been programmed, Finally we apply the program to underground power house of XILUODU hydroelectric station to Carry out Stability analysis under excavation and get some satisfactory computation results.
