| Abstract: | Graphical method has been used to determine two layer soil parameters, but it is more difficult and the results obtamed are less accurate when the actual soil construct is complex. Based on Powell algorithm, an optimal estimation method to determine the soil parameters is presented in this Paper. The calculation is quite convenient and the results obtained are more reasonable and accurate than other optimal algorithms becuase the derivation that is necessary in other algorithms is avoided and the convergent speed is higher. |
