长淮卫淮河大桥船撞设防标准研究

Research on Fortification Criteria for Ship Collision of Changhuaiwei Huaihe River Bridge

以长淮卫淮河大桥为依托工程,介绍桥梁船撞设防标准的确定方法。基于风险的思想,参考《重庆市三峡库区跨江桥梁船撞设计指南》,对长淮卫淮河大桥在2012年、2022年和2050年通航密度下进行船撞风险分析,并根据风险分析结果,提出进一步降低桥墩船撞风险的建议和措施,为桥梁船撞设计提供技术支撑。

With Changhuaiwei Huaihe River Bridge as a support project, this paper introduces the methods to determine fortification criteria for ship collision of bridges. Based on the idea of risk and thinking of ＂Guide for Design of Ship Collision of Cross- river Bridges in Three Gorges Reservoir Region of Chongqing＂, the paper analyzes the risks of ship collision of Changhuaiwei Huaihe River Bridge at traffic densities in 2012, 2022 and 2050, and proposes suggestions and measures for further reducing the risks of ship collision of bridge piers according to the results of risk analysis to provide technical support for design of ship collision of bridges.
