GUANDI HYDROPOWER STATION IN YALONG RIVER STUDY ON STABILITY AND REINFORCEMENT OF ZHUZIBA MATERIALS YARD HIGH SLOPE

Basised on the geological survey report,through the analysis of the slope structure and the slope deformation,to evaluate the stability of excavated high slope. By use of rigid limit equilibrium method and RockSlope quantitative calculation, judging damage model and reinforcement measures. Theoretical analysis and monitoring data show that the whole stability of permanent crown yard slope is good, but because of the adverse impact on the structure, Small landslides and rockfall are main types of geological hazards, it should be reinforced.
