摘　　要：为了提升桥梁独柱墩的抗倾覆性能,确保桥梁结构的安全与稳定,通过介绍桥梁独柱墩工程的基本概况,包括桥梁类型、结构特点等,详细分析了倾覆荷载的产生原因及影响因素。在此基础上,深入探讨了独柱墩桥梁的抗倾覆设计,包括曲率半径的合理确定、梁端双支座间距的优化设计,以及独柱墩与梁体之间不同连接方式的比较与选择。通过理论分析与计算,提出了有效的抗倾覆设计策略。研究结果表明:合理的曲率半径、合理的支撑间距、稳定的节点形式可有效提高独柱式桥墩的抗倾覆性能,为该类型桥梁的设计和建造提供坚实的理论支撑与技术保证。In order to improve the anti overturning performance of bridge single column piers and ensure the safety and stability of bridge structures,this paper introduces the basic overview of bridge single column pier engineering,including bridge types,structural characteristics,etc.,and analyzes in detail the causes and influencing factors of overturning loads.On this basis,the anti overturning design of single column pier bridges was deeply explored,including the reasonable determination of curvature radius,the optimization design of the spacing between double supports at the beam end,and the comparison and selection of different connection methods between single column piers and beams.Through theoretical analysis and calculation,effective anti overturning design strategies have been proposed.The research results indicate that reasonable curvature radius,reasonable support spacing,and stable node form can effectively improve the anti overturning performance of single column bridge piers,providing solid theoretical support and technical guarantee for the design and construction of this type of bridge.
