Comparative Analysis of Reinforcement Programs of System Anchors for Unloading Rock Slope
Based on hyperbolic nonlinear elastic constitutive model of unloading rock mass, the anchoring rock mass of excavation spillway of a hydropower station has been taken for the study. And considering the impact of excavation unloading process, three reinforcement programs are compared and analyzed. Overall, the constraint by system anchors on deformation of the spillway slope is limited. If the limit on the slope deformation is higher, pre-stressed cables are necessary.
