| Abstract: | The finite element method of the classical Goodman joint element of zero thickness is reviewed. A new kind of 3D-interface element of zero thickness with 8 nodes is derived with special regard to the vertical bearing characteristic of the group-pile. The pile-soil interaction characteristic is modeled in the numerical analysis by choosing different rigid coefficients. The above research has been exercised in the numerical analysis and predicted of P-S curve of a group-pile in an example, and also been utilized to study the P-S curve variation of the group pile under different conditions. |
| Keywords: | pile-soil interaction 3D-interface unit with 8 nodes P-S curve of group pile numerical analysis |
