海口世纪大桥是一座在建的主跨３４０ｍ的双塔双斜索面预应力混凝土斜拉桥。由于海口市是我国 主要的强风区，在施工设计风速下世纪桥施工阶段存在不安全的因素。为保证大桥的抗风安全，受建设单位委 托，设计单位完成了世纪桥施工双悬臂结构风致抖振反应控制的研究和设计，并经评审通过，建设单位决定采 用。本文在对世纪桥施工双悬臂结构抗风安全性进行评定的基础上，介绍了所完成的世纪桥施工双悬臂结构风 致抖振反应控制方案的原理和设计方法。并通过对设计方案控制效果的理论分析和风洞试验，验证了世纪桥施 工阶段风振控制设计的可行性和可靠性。
The Haikou Century Bridge is a 340m double-tower double-inclined cable-stayed prestressed concrete cable-stayed bridge under construction. As Haikou City is the main strong wind region in our country, there is an unsafe factor in the construction stage of the Bridge under the construction design wind speed. In order to ensure the wind-proof safety of the bridge, commissioned by the construction unit, the design institute completed the research and design of the wind-induced chattering response control of the double-cantilever construction of Century Bridge and was approved by the construction unit and adopted by the construction unit. Based on the evaluation of the anti-wind safety of the double-cantilever structure of Shiqiao construction, this paper introduces the principle and design method of the control scheme of the wind-induced chattering response of the double cantilever structure of the Shiqiao construction. Through the theoretical analysis of the control effect of the design scheme and the wind tunnel test, the feasibility and reliability of the wind-induced vibration control design during the construction of the Shiqiao Bridge are verified.
