Karl Valley Quarry is the main quarry for the construction of the Pubugou Hydropower Project. With its developed faults, veins, dense joint-relief zones, deep pressure-relief zones and fissure, the slope has the possibility of integral and partial instability in the densely blasting and excavating process). Based on the rock elastic-plastic equivalent constitutive relations of joint-anchoring, by using the elastic-plastic element finite element method, the slope excavation and reinforcement as well as the stability is numerically simulated and analyzed. In addition, the reasonability of the initially drafted schemes for construction sequences and anchoring are evaluated and some valuable and instructive suggestions have been proposed to the engineering construction relevantly.
