Research on dynamic simplified calculation method of all-vertical-piled wharf in offshore deep-water
摘要
Abstract
All-vertical-piled wharf in offshore deep-water subjects to dynamic load for a long time, such as wave load and impact load, only static analysis cannot meet the requirement of the engineering design. In order to research dynamic simplified calculation method of all-vertical-piled wharf in offshore deep-water, an embedded solid finite element model and the structure and soil interaction 3D elastoplastic finite element model are established by using ABAQUS software. Based on the established finite element model, the natural vibration characteristics of above-mentioned wharf are studied by employing modal analysis method. The analysis indicates that fundamental period of structure is relatively long, and it is close to periods of wave load and impact load;so dynamic response of structure is remarkable. Then the further calculations have shown that the results of dynamic finite element and the theory formula of the dynamic amplification coefficient of single-degree-of-freedom system under wave load and impact load are in good agreement;so dynamic response simplified calculation method of the wharf is put forward. On this basis, the dynamic simplified calculation method is proposed combining with m method, p-y curves method and NL method. In comparison with the dynamic finite element method, the dynamic simplified calculation method is reliable.关键词
