摘要
杭州湾大桥为目前世界最长的跨海公路大桥,包括南航道和北航道两座大跨度桥梁。对杭州湾大桥北航道桥成桥状态、最大双悬臂状态及最长单悬臂状态进行了动力特性分析,介绍了节段模型风洞试验的主要内容、试验结果, 据此分析评估了该桥的抗风性能,并得出了一些有益的结论。
The Hangzhou Bay Bridge is the longest highway bridge across the sea in the world, consisting of south and north long-span bridge. This paper analyzes the dynamic performance of construction and operation of North Hangzhou Bay Bridge, and introduces the wind tunnel results of four types cross section models, including vortex-induced vibration, flutter critical wind speed, flutter derivatives, buffeting response. The assessment to wind-resistant performance of the bridge is given based on the test results, with some conclusions.
