摘要：

The FEM with a new fracture-damage model has been adopted to analyse the stability of the high slopes of Three Gorges Flight Lock. In the analysis the generation of subcracks at joint tips and its additional deformation to rock mass as well as the possibility of its further extension of subcracks are considered under compressive-shear stress condition. The effect of rock bolts of different schemes to reduce the damage evolution zones of joints and the slope deformation are studied. A comparison of research results from a new model with the previous work is made also.
