荷麻溪单索面部分斜拉桥抗风稳定性设计

Study for the wind-resistant stability in Hemaxi extra dosed bridge with single plane cable

荷麻溪特大桥是目前国内跨径最大的单索面双塔部分斜拉公路桥,为确保桥梁抗风稳定性能,专题进行了抗风性能研究,通过分析该桥动力特性,对桥梁在最大悬臂施工状态和成桥状况下进行了抗风稳定性设计,计算结果表明该桥具有良好的抵抗台风能力。

This paper analyzes the dynamic behavior and wind-resistant stability of Hemaxi bridge, which is the longest extra dosed bridge with single plane cable and double towers at the same types in China nowadays. The result of ease study shows that the construction of this bridge, in the maximum cantilever and the completion state has fairly good capacity of typhoon-resistant stability.
