Study on One-dimensional Creep Constitutive Relations for Clay in Zhanjiang Area

Based on the data of rheological test,the one-dimensional rheological properties of clay in Zhanjiang area are studied, the creep curves and stress-strain curves were analysed. Several styles of classical component models and improved model which was composed of fractional derivative component are chosen to describe the creep characteristics. Through the compaorson and analysis,we propose that modified Burger model and Burger model can describe the one-dimensional creep better than others ones. More over,a simple empincal model is presented.
