摘要
泰州大桥主墩位于航道边缘,可能遭受船舶的撞击。为保护大桥,综合考虑多种因素研究大桥中塔墩防船撞方案。针对泰州大桥三塔悬索桥型,结合通航船舶规划、桥梁参数、桥墩基础特点,开展防撞研究,提出针对性防撞方案,进行防撞特性计算分析,确定防撞方案的技术、经济特性。通过有限元数值仿真技术,研究泰州大桥在船舶撞击下的安全性和防撞方案的有效性。
The risk of ship collision to the center tower located at the edge of navigation channel of Taizhou Yangtse River Highway Bridge is expected.To protect the bridge,this research integrates a variety of factors to study the protection system of the center tower.Aiming at the suspension bridge with three-tower-span,with combination of ship navigation planning,bridge parameters and characteristics of bridge foundation,the ship collision research is carried out and protective measure scheme is proposed.Calculation and analysis for crash characteristics are carried out to determine the technical and economic characteristics of the protective measures.The safety of the bridge and effectiveness of the protection system under ship collision is studied by applying the dynamic FEM techniques.
