The result of the creep test performed in this study shows that the creep deformation of soils is represented by the equation which is the combination of the equation expressing the behavior of a visco-plasto-elastic model and non linear time dependent function, tα. Then, a new rheological model which consists of a series of the visco-plasto-elastic model and modified Bingham model is proposed to describe the creep deformation of soils.
