Abstract

Dynamic properties of compacted cohesive soils are required in most of the civil engineering constructions. These include construction of dams, dikes, embankments, liners and levees. Dynamic properties are highly important for determining the engineering behaviour under dynamic as well as cyclic loading. In the present study a series of resonant column tests were performed on compacted cohesive soil to determine its dynamic properties. The dynamic properties studied were shear modulus, damping ratio and Poisson’s ratio of soil. The effects of confining pressure and shear strain on the dynamic properties of the compacted cohesive soil are discussed. It is observed that there is increase in shear modulus and decrease in damping ratio as well as Poisson’s ratio of the soil with the increase in confining pressure. It is also observed that there is reduction in shear modulus and increase in damping ratio and Poisson’s ratio of the soil with increase in shear strain.
