A nonlinear visco-elastic–plastic creep constitutive model is established combined with a Bingham creep model and a Kelvin creep model. Additionally, the soil creep parameters of an undisturbed soil specimen from the Wuxi subway engineering investigation site are determined according to triaxial cre...
