| Abstract: | The author uses the three-dimension viscoelastic model to represent the time-order of the subsidence of soft grounds of expressway.Based on the data collected from observing the set-tlement of the soft grounds and the model parameters determined by optimal counter-analysis,the ultimate settlement can be forecast and the reliability of the calculations greatly improved.Thus it is of great help to provide a good guidance to the design and construction of soft grounds of ex-pressway. |

| Keywords: | expressway grounds viscoelastic model optimal counter analysis ultimate settle |
