Abstract: The visco-elastic-plasticity model is often used to solve soil creep problems. The key point is how to determine the parameters for the complex model. These parameters have to be obtained with the laboratory tests. However, the soil creep process may last for several decades or even hundreds of years, while the laboratory tests can not be carried out for more than several months at most. Therefore, it is very important to estimate the reasonable parameters for FE analysis by extrapolating the laboratory test results. In this paper, a statistical method is presented to give an estimation of the parameters for the visco-elastic-plasticity mode. The estimated parameters have been successfully used to assess the creep tendency of Tianjin Harbor and several other projects in which the creep effect is concerned.

Key words: visco-elastic-plasticity model, FE analysis, statistical method, parameters, creep
