摘　　要：在大气边界层风洞进行了"珠江城"商务写字楼大比例尺(1:150)模型风洞试验,通过对风洞试验数据分析,获得了基础等效静风荷载及结构顶部风致加速度响应。并将其结果与其它较小比例尺的两个风洞试验结果相对比,分析了模型几何缩尺比、周边建筑及平均风剖面对试验结果的影响。获得的结果可以为此结构设计提供风荷载,同时也为其他建筑的抗风设计和风洞实验提供技术参考。Wind tunnel test for Pearl River Tower with a large scale model（1：150） was conducted in a boundary layer wind tunnel.This paper presents some selected results of the base equivalent static wind loads and wind-induced acceleration responses from the analysis of the data obtained in the wind tunnel test.In addition,the results from two previously conducted wind tunnel tests with smaller scales of the building models are used for comparative study,and the effects of geometry scale ratios,surrounding building conditions,and mean wind speed profile are investigated.The outcomes of this study are expected to be useful to determine the wind loads on the tall building in the design stage,and also provide guidelines for the design and wind tunnel tests for other similar structures in the future.
