“珠江帆影”高层建筑群风洞试验研究

本文介绍在广州市珠江畔兴建的“珠江帆影”曲面外型高层建筑群工程,采用1/100比例模型在中国气动力中心的大型低速风洞中进行的不同风速、不同迎风角下均匀风场的测压和测力试验。提出了确定曲面形状体型系数的初步意见,并对曲面外形高层建筑群的受风特性、楼体之间的相互干扰以及群体中主楼和主楼单体间的差异进行了探讨。同时,还进行了水洞和烟风洞的模型流态观察。

Experimental Research on a Group of Curve-Shaped Highrise Buildings in Wind Tunnel Test

This paper introduces the test results of a group of buildings with curved shapes along the Pearl River in Guangdong Province. The scale of the model used was 1/100 and the tests were carried out in China Aerodynamic Center. The pressures and forces on buildings in uniform wind field were measured under different wind velocities with different windward angles. The shape coefficients for curve-shaped buildings are proposed in the paper. The characteristics of curve-shaped buildings subjected to wind load and the interference due to adjacent buildings are discussed.The stream mode of the building models arc also observed in water tunnel and smoke tunnel tests.
