| Abstract: | For soft clay which has rheological property, the selection of model is very important for describing mechanical behaviors. Classical model has some disadvantages for describing rheological property of clay; and the classical rheological model and the fractional derivative rheological model are analyzed and compared. The latter is more accurate than the former; and it has a wide application area. |

| Keywords: | rheology viscoelastoplasticity fractional derivative |
