摘要
在跨河大桥安全运营领域中,船撞风险防控对保障交通命脉与公众安全意义重大。本研究聚焦某跨河大桥船撞风险分析及防撞设施优化,通过剖析桥梁结构参数、通航环境特征与桥墩暴露性,系统阐述风险评估模型构建、碰撞概率计算及结构失效风险量化。结果表明,采用钢-复合材料组合防撞设施优化的分层设计效果明显提高,明晰了风险分布与防护方案的适配价值,可为桥梁工程从业者提供可操作的风险防控参考,助力跨河大桥抗撞技术发展,推动和实现桥梁安全运营目标达成。
In the field of safe operation of river-crossing bridges,the prevention and control of vessel collision risks are of great significance to ensure traffic lifeline and public safety.This study focuses on the vessel collision risk analysis and anti-collision facility optimization of a river-crossing bridge.By analyzing the bridge structure parame⁃ters,navigation environment characteristics and pier exposure,the risk assessment model construction,collision probability calculation and structural failure risk quantification are systematically expounded.The results show that the layered design effect of steel-composite composite anti-collision facilities optimization is obviously improved,and the matching value of risk distribution and protection scheme is clarified.It can provide operable risk preven⁃tion and control reference for bridge engineering practitioners,help the development of anti-collision technology of river-crossing bridges,and promote and realize the goal of safe operation of bridges.
