| Abstract: | Damage evolution equation of jointed rockmass and a 3-D brittle elastic fracture damage constitutive equation are established according to the Betti's reciprocal-energy theorem and by considering energy transformation and interaction in the process of joint cracks propagation. The constitutive model is used for the high slope of Three Gorges shiplock. A 3-D non-linear FEM computation is made for the analysis on excavation unloading stability for jointed slope rockmass and satisfactory computational results are obtained. |

| Keywords: | brittle elasticity damage evolution equation stability of slope unloading |
