AbstractUnconfined impact compression tests were used to measure dynamic parameters of soil samples in the domains of stress wave propagation and dynamic deformation. The high-frequency equivalent Young's modulus, which was determined by the reflection theory of one-dimensional elastic stress waves, increased exponentially with water content. The low-frequency equivalent Young's modulus, which was defined as the initial gradient of a stress-strain curve, decreased exponentially with increasing water content. The high-frequency equivalent Young's modulus was one to two orders of magnitude larger than the low-frequency one. Water content, height of soil samples and drop height affected the dynamic stress-strain relationships of the soil samples. The Maxwell's viscoelastic fluid model described the stress-strain relationships well, and the values of the model parameters varied with water content and frequency.
