Analysis on the characteristics of the wind at the Qipanzhou Yangtse River bridge based on a short-term investigation
摘要
Abstract
Qipanzhou Yangtse River Bridge is of long span, light and soft structure. Its design and construction are extremely sensitive to strong wind. Therefore, an automatic observation station, Qipanzhou automatic weather station, is established near the bridge to observe the characteristics of the wind at the bridge. On the basis of the wind data observed at Qipanzhou weather station and data collected from Huangshi whether station from Feb. 2011 to Jan. 2012, the mean wind speed, extreme wind speed, extreme wind speed are analyzed in details in this paper. The results indicate: 1) most of the time, the monthly average wind speed, maximum wind speed and extreme wind speed at Qipanzhou weather station are larger than Huangshi weather station; 2) As the wind speed increases, the correlation between the daily maximum wind speed at bridge and Huangshi weather station decline gradually until irrelevant; 3) the predominate wind directions at Qipanzhou weather station are converging SSE and NW, in some degree different from those at Huangshi weather station, which are E and NW and non-converging.关键词
