The elasto?plastic properties of clays are modeled using the stress?strain relationship with hardening of hyperbolic type. this model is so?called Mesri model. At same time, the Singh?Mitchell′s strain rate?time function is adopted to describe the clay behavior?creep. Some results of indoor tests about the Shanghai silt?clay are carried out. The Mesri model and Singh?Mitchell′s function combined with the test data is proposed in the paper to study the creep of clays. A creep formula for the Shanghai silt?clay is obtained. There only few parameters in the formula are needed to determinate. It is easy to use and feasible for engineering practice.
