斜拉桥拉索的风(雨)激振及控制

RAIN-WIND INDUCED VIBRATION OF CABLES ON CABLE-STAYED BRIDGES AND ITS CONTROL

目前,国内建造了大量的斜拉桥。随着斜拉桥跨度的增大,拉索的风致振动及风雨激振问题越来越突出。本文总结了国际上的有关研究,特别是拉索风雨激振及控制研究的成果,指出了这一领域中有重要意义的研究方向。

In the past decades, a large number of cabled-stayed bridges have been constructed in various distracts in the world. With the increase of spans of the bridges, problems of wind-induced and rain-wind induced vibrations become more and more serious. This paper gives a review of the achievements of the research works on these problems, especially on the rain-wind induced vibration and its control. As a result of the investigation, some research directions on this subject have been pointed out and been discussed.
