| Abstract: | The characteristics of the environment which the large sea-crossing bridges are in and the anti-collision requirements in the circumstances are studied.Anti-collision solutions for the bridge piers at the main navigable span of large sea-crossing bridges are devised and investigated.Comparison of the solutions shows that the solution of attaching energy-dissipation steel jackets to piers is the most suitable one.The jackets occupy less waterway space and are easier to manufacture and maintain,therefore,more economical.The modular double layer steel jacket structure is developed.The structure effectively dissipates energy and facilitates automatic manufacturing.The effectiveness of the solution is verified through numerical simulation based on finite element analysis. |
