摘要
介绍上海长江大桥船撞安全方面的研究成果。采用碰撞有限元数值模拟方法,对上海长江大桥在船舶撞击下的动力反应进行分析,获得船舶撞击力和结构的动力反应;对大桥的防撞套箱的防撞效果进行评价,包括对船舶撞击力的消减效果、对桩基础的保护效果等。本文的数值模拟结果为大桥基础设计和防撞套箱的优化设计提供技术支持。
This paper presents the research findings of the safety performance of Shanghai Changjiang River Bridge against ship collision, analyzes the dynamic responses of the Bridge subjected to the ship collision, using the finite element numerical simulation method, obtains the collision force and dynamic responses of the structure and also evaluates the effect of the anti-collision boxed cofferdams, including the collision-reducing effect and protection capacity of the cofferdams for pile foundations. The results of the numerical simulation herewith contribute the technical support to the design of the pile foundations and the optimal design of the cofferdams of the Bridge.
