Conventional and wetting triaxial experiments were carried out on coarse grained materials for dam construction with a large static and dynamic triaxial tester. The dynamic characteristics of coarse grained materials after wetting deformation were studied, and the results were compared with those of conventional triaxial dynamic experiments. The experimental results show that the dynamic characteristics of coarse grained materials are greatly affected by wetting deformation, and the dynamic performance parameters of coarse grained materials are attenuated to a certain extent. The Hardin-drnevich model parameters of the two experiments were compared and analyzed. It was found that wetting deformation had a significant effect on k2 and λmax, and the numerical values were attenuated, but the effects on n and k1 were not significant.
