| Abstract: | The optimization problem is solved by using an external penalty function and a simple method. The area of pile shaft and the optimal result on certain load have been obtained. So it has theoretical meaning and practical value to have optimum design on the diameters of the pile shaft and the expanded bodies. The optimal program is used not only in the single soil but also the multilayer soil. The practice shows that it has theoretical meaning and practical value. |
| Keywords: | variable cross-section pile the optimal design object function simple method |
