| 標(biāo)題 |
| 西堠門大橋橋址處風(fēng)場(chǎng)特性研究(50 卷) |
| 英文標(biāo)題 |
| Study on wind field characteristic in site of Xihoumen bridge |
| 摘要 |
| 為了對(duì)大跨度橋梁抗風(fēng)評(píng)估提供可靠依據(jù)，在西堠門大橋跨中安裝了4個(gè)3維超聲風(fēng)速儀，對(duì)橋位處風(fēng)場(chǎng)進(jìn)行長期連續(xù)觀測(cè)，獲得了橋位處大量風(fēng)速樣本。經(jīng)過對(duì)實(shí)測(cè)風(fēng)速數(shù)據(jù)的分析，得到了平均風(fēng)速和風(fēng)向、紊流強(qiáng)度、紊流功率譜密度函數(shù)等風(fēng)場(chǎng)特性，以及紊流強(qiáng)度、陣風(fēng)因子和摩阻速度 |
