Abstract

This paper presents a theoretical study of pore fluid induced damping of saturated soil in resonant column tests. The solid skeleton is treated as equivalent linear. Pore fluid induced damping due to Biot flow is evaluated based on the spectral response of the soil column under harmonic excitations. Closed-form analytical solution indicates that pore fluid induced damping is frequency and hydraulic conductivity dependant. At the first resonance, pore fluid induced damping is dependent on a dimensionless hydraulic conductivity parameter K. For K within the range of 10 ^-3 to 10, corresponding to coarse sands and gravels, pore fluid induced damping may have an important contribution to total soil damping, especially at small strain levels.
