摘要
以东海大桥桥墩防撞方案设计为背景,论述复杂环境下桥墩防撞设计的基本方法,对比若干可行方案。引入港口工程中常见的大直径薄壁圆筒结构,构造一种新型的桥墩防撞系统,并给出具体构造,其良好的受力条件和地基适应性表明:用于桥墩防撞设施具备一定的可行性。设计构造措施对同类环境下桥梁防撞设计具有一定的参考意义。
The ship-bridge collision-prevention design of Donghai bridge is taken as an example to the design of ship-bridge collision-prevention for the bridge located in complicated environment and schemes with feasibilities engineering are introduced be a reasonable selection f are compared. Large-diame to construct a new type of an ter thin shell cylindrical structures widely tl- collision system, with idance system due to detailed structures discuss sev used in the presented. It eral port the favorable mechanical properties and adaptability of foundations of large-diameter thin shell cylindrical structures. Thedetailed structures of ship- bridge collision avoidance system presented in this paper may provide some reference for the design of ship-bridge collision avoidance system of bridges under similar environment.
