Abstract：To obtain the dynamic deformation characteristics of saturated red clay under different test conditions, the GDS dynamic triaxial test system was used to investigated the saturated red clay in Chenggong area of Kunming, and the effects of confining pressure, frequency and consolidation ratio on the dynamic deformation characteristics of remolded saturated red clay were discussed. The test results show that with the increasings of confining pressure and dynamic load frequency, the dynamic stress for the same strain is required greater, and the dynamic elastic modulus is increased with decreased damping ratio. With the increasing of consolidation ratio, the dynamic stress for the same strain is required smaller, and the dynamic elastic modulus is decreased with increased damping ratio. Through Hardin-Drnevich hyperbolic model, the dynamic constitutive relation of saturated red clay is fitted with good fitting effect. The fitting parameters under various test conditions are given, and the maximum dynamic elastic modulus and the maximum dynamic shear modulus are calculated.The maximum dynamic elastic modulus and dynamic shear modulus are increased with the increasings of confining pressure and dynamic load frequency, and those are decreased with the increasing of consolidation ratio.
