厦漳跨海大桥风速测量与研究

Monitor and Research Wind Speed for Xiazhang Bridge

随着桥梁建设的不断发展,桥梁的跨径越来越大。桥梁所受到的自然灾害也越来越多。风作用下桥梁结构的安全性已成为人们极为关注的重要问题,同时也给桥梁风工程研究带来更大的机遇和挑战。21世纪的跨海大桥工程中出现了许多超大跨度的斜拉桥和悬索桥,在台风多发的海域建造柔性的超大跨度桥梁,抗风安全将是最重要的控制因素。本文采用FY-W2风速风向仪对福建厦漳跨海大桥进行风速测量,为后期桥梁风雨振的研究提供数值依据。

With the continuous development of bridge construction, the bridge span is increasing, The bridge is also destroyed by more and more natural disaster. The safety of bridge structure with wind load has become a very important issue of concern, at the same time it gives us more opportunities and challenges for bridge wind engineering. There are many large span cable - stayed bridges and suspension bridges across the sea in 21st Century. Construct flexible bridges of larger span in the sea prone to typhoon. Wind resistance of bridges is the most important control factor. We used anemometer of FY - W2 to monitor wind speed for Xiazhang bridge of Fujiart province, and provide for numerical basis to research wind - rained vibration later.
