| Abstract: | To adapting to the hydrological conditions in the Three Gorges reservoir area, the application ofnew-style overhead vertical wharf with large-diameter pile and span will be a tendency. Taking the Naxigou wharf in Chongqing district as an example, the 3D finite element model for the structure is built by finite element method and then a modal analysis on it is given to study preliminarily the dynamic property of this structure and evaluate the safety of the wharf structure. |
| Keywords: | large-diameter pile large span new-style structure model analysis |
