桥梁防撞研究技术与方法

针对桥梁防撞研究这一工程界的热点问题，概述了桥梁防撞研究的一般方法和思路，简述了船一桥碰撞力学的计算方法和船撞桥的风险概率分析方法，同时结合上海长江大桥工程，对主通航孔桥墩进行了防撞力标准和防撞方案研究。利用非线性有限元分析技术，对桥墩设计的防撞方案进行了性能分析，验证了防撞设施的有效性。

Techniques and Methods in Ship-Bridge Collision Avoidance Research

For bridge anti-collision research its methods and ideas are introduced briefly,also the calculation methods of ship-bridge collision mechanics and the analysis methods of ship-bridge collision risk are summarized.In combination with Shanghai Yangtze River Bridge Project,the criteria and schemes of anti-collision for its main piers are studied.By using non-linear FEM the anti-collision of pier design is analyzed and the effectiveness of the anti-collision facilities is validated.
