Abstract
Dynamic shear modulus and damping ratio are two main parameters for describing the dynamic performance of aeolian soils. This paper presents the influence of the confining pressure, the consolidation ratio and the vibration frequency on the dynamic shear modulus and the damping ratio of aeolian soils with a series of dynamic triaxial tests. Experimental results show that the dynamic shear modulus of aeolian soils increases with the confining pressure and the consolidation ratio, while the damping ratio decreasing with them; both of the dynamic shear modulus and the consolidation ratio increases with the vibration frequency, but the influence is less than that of the confining pressure and the consolidation ratio.
