山区地形的钢桁拱桥风场特性研究

以山区某大桥为背景,对桥址处风特性进行了一年的实测,得到了平均风速,湍流强度等强风特性。分析结果表明,对于这类山地地貌,脉动风的影响较大,其湍流强度和阵风因子远大于规范相关值和平原地区测得的结果。

Study on the wind characteristics of the steel truss arch bridge in the mountainous terrain

Taking a bridge in a mountain area as the background, it made a one-year measurement on the wind properties on the bridge site,colleted an average wind speed,turbulence intensity and other characteristics of strong winds.The results show that for this type of mountain landscape,the impact of fluctuating wind is more,the turbulence intensity and gust factor is much larger than standard relevant number and measured results in plain areas.
