The compaction quality of rockfill materials directly affects the deformation of face dam.The application of 32t vibratory roller in dam construction in granite area is rarely reported.In order to guide the rolling construction of main rockfill in Wuyue pumped storage power station，this experiment was carried out to study the effects of rolling passes and sprinkler rate on dry density，porosity and permeability coefficient of main rockfill.The results show that the dry density of rockfill increases with the increase of rolling times，and the porosity and permeability coefficient decrease with the increase of rolling times.Increasing the water spraying rate is beneficial to the rolling and dry density of rockfill.Based on the operation characteristics，design indexes and economic performance of pumped storage power station，the recommended rolling parameters of 32 t vibratory roller for Wuyue pumped storage power station are paving thickness 90 cm，watering rate 10 %，rolling 8 times.
