Abstract
The dynamic responses of soils are important engineering properties, especially for soils with high organic contents, because these soils can underlie critical support structures such as highway bridges or levees. Consequently, the initial tangent shear modulus (Gmax), secant shear modulus ratio (G/Gmax), and damping ratio (D) are important parameters in evaluating the dynamic soil behavior for soils subjected to earthquake, wind, waves, traffic, and equipment vibration. in this study, these dynamic properties of organ bentonites were quantified experimentally using resonant column tests. the results from this study were evaluated in terms of the effect of shear strain, organic content, and plasticity index. the organ bentonites tested in this study were engineered with an organic phase that was controlled in terms of structure and density of loading. the results indicate that the total organic carbon content reduced the net surface charge on clay particle, which in turn increased the bonding between the organic cations and clay surface. the resistance is then increased, leading to increase in stiffness. © 2012 American Society of Civil Engineers.
