摘　　要：随着经济及技术的进步,高墩大跨桥梁因其独特的地理适应性和经济性,在山区、河谷等复杂地形中越来越常见。然而,随之而来的结构稳定性问题,特别是在强风环境下的抗风性能,成为桥梁工程领域关注的焦点。以在建湾档河大桥主桥为例,采用有限元分析方法,探讨高墩大跨桥梁的抗风性能。研究结果显示,不同风荷载工况下桥墩墩底横桥向往往为最不利情况,该研究结论可为相关工程实践提供理论支持与设计指导。With the progressive economy and increasing technology,high-rise pier and large-span bridges are particularly common in complex terrains such as mountainous areas and river valleys due to their unique geographical adaptability and economy.However,the accompanying structural stability issues,especially the wind resistance performance in strong wind environments,have become a focus of attention in thefield of bridge engineering.This article,taking the main bridge of the being built Wandang River Bridge as an example and usingfinite element analysis method,explores the wind resistance performance of high pier and large-span bridges.The results show that the transverse direction of the bridge pier bottom is often the most unfavorable situation under different wind load conditions.Relevant conclusions of this article aim to provide theoretical support and design guidance for related engineering practices.
