Abstract Time effects obviously exist in the foundation pit rebound in soft ground. The triaxial unloading creep tests on soft clay in Shanghai is described；and the unloading stress path is designed to be close to the field stress path of the soil in the bottom of foundation pit. A five-element model is presented based on the test results. Comparisons between test curves and the ones derived from the model are conducted. The results show that two of them are very close to each other.
