| Abstract: | Based on the software LS-DYNA-970 of finite element method on centered finite difference ,this paper is focus on analyse the hybird wharf of Caissons and high pile using the three-dimensional FEM model. During the study we focus on the natural vibration, the response acceleration and also the strain and stress distribution of the structure. And got the acceleration data of points at different hight. This can help accumulate experience of new structure, which can also provides reference for modifying the current technical specifications. |
