%X 通过对方型截面高层建筑进行一系列单自由度气弹模型测振试验，分析了在不同间距比下相邻建筑对目标建筑的顺风向动力干扰效应。研究结果表明：干扰效应与间距比成反比，随着间距比增加，干扰效应减弱。在串列布置时，施扰建筑增大了目标建筑的来流风速和湍流度，导致干扰效应主要表现为放大效应，在施扰建筑的高速尾流边界时，放大效应达到50%；在并列布置时，干扰效应随间距比增大，从抑制效应转变为放大效应。<br />
A series of single-degree-of-freedom aeroelastic model vibration measurements were carried out on high-rise buildings with square cross-sections to analyze the downwind dynamic interference effect of adjacent buildings on the target buildings under different spacing ratios. The results show that the interference effect is inversely proportional to the spacing ratio, and weakens with the increase of the spacing ratio. In the series arrangement, the disturbing building increases the incoming wind speed and turbulence of the target building, resulting in the interference effect mainly manifested as an amplification effect, which reaches 50% at the high-speed wake boundary of the disturbing building. When the juxtaposition is arranged, the interference effect changes from an inhibition effect to an amplification effect with the increase of the spacing ratio.
