摘　　要：随着我国东南沿海地区超高层建筑不断涌现,对于高空风环境参数的现场实测和分析工作日显突出,这部分内容亦超出了我国建筑结构荷载规范的要求。上海环球金融中心大厦位于上海市浦东陆家嘴地区,周边超高层建筑排列密集,场地条件非常复杂,场地类别介于C类和D类之间。对上海市环球金融中心施工阶段高度为246～343 m的中强度脉动风特性进行了现场实测,统计并比较了不同高度和来流方向的紊流强度、阵风因子和紊流积分尺度,对水平和垂直方向来流脉动风功率谱密度函数进行了曲线拟合。As super high-rise buildings continue to emerge in the southeastern coastal areas of China, the measurements in site and analysis of high-altitude winds environmental parameters get increasing importance, which also exceeded the load code for the design of building structures. Shanghai World Financial Center Building located in Shanghai Pudong Lujiazui area, surrounded by high-rise buildings with intensive, is in the extremely complex site condition between C and D. Long time observation and corresponding statistic analysis of natural wind at Shanghai World Financial Center with the height of 246 - 343 m were performed. The turbulent characteristics with different heights and directions, including turbulence intensity, gust factor and integral length scales, were summarized based on a large amount of measured data, and horizontal and vertical wind spectrum were curved.
