In order to deeply study the dynamic characteristics of muddy soft soil layer in the Jianghan basin, we conduct a series of undrained dynamic tests using a self-vibrating column tester, and analyze the characteristics of dynamic shear modulus ratio G/G0 and damping ratio λ with the change of shear strain γ for the soft soil samples in this area. Different dynamic constitutive models are used to fit the G/G0-γ and λ-γ curves of the muddy soft soil, and the optimal fitting curves are obtained. The results indicate that the nonlinear characteristics of soft soils in the Jianghan basin show strong regional features and are obviously different from the average level in China. The findings can provide more knowledge about dynamic characteristics of the muddy soft soils in this area, and can be used as a reference when the measured dynamic parameters of muddy soft soils are insufficient.
