| Abstract: | In accordance with the Duncan Chang nonlinear elastic soil model,that,the DFP method is used to draw up optimization programme for parameteric identification of the parameters in this model,it is verified combined with a calculation example of the practical engineering project,and its feed back analysis is carried out too.From final results are shown that the DFP method is a good constrained optimization calculating method with quick convergence and high accuracy,and the results of feed back analysis can conform well to the reality of engineering pratice. |
| Keywords: | Duncan Chang nonlinear elastic soil model DFP method feed back analysis |
