摘　　要：公路桥梁的抗风设计是确保桥梁安全性和耐久性的重要环节。随着大跨度桥梁的普及,风荷载对桥梁的影响日益突出,导致传统设计方法无法完全满足现代工程需求。文中从风荷载的作用机理、抗风设计的基本原则及关键技术等方面进行探讨,提出了适用于大跨度桥梁的抗风设计策略和优化措施,为提升桥梁的抗风能力提供理论依据和实践指导。Wind resistant design of highway bridges is an important part of ensuring bridge safety and durability.With the popularity of large-span bridges,the impact of wind loads on bridges is becoming increasingly prominent,leading to traditional design methods being unable to fully meet modern engineering requirements.The article explores the mechanism of wind load,basic principles and key technologies of wind resistant design,and proposes wind resistant design strategies and optimization measures suitable for large-span bridges,providing theoretical basis and practical guidance for improving the wind resistance capacity of bridges.
