［摘要］在边界层风洞中完成了测压管长分别为0-6，0-8，1-0，1-2，1-5m的矩形截面高层建筑刚性模型的同步测压试验。研究了不考虑测压管道系统修正时，测压管道长度对建筑表面风压特性及脉动风压相关性的影响。结果表明：测压管道的长短对平均风压系数影响较小，但对脉动风压的影响较大，脉动风压系数在迎风面的偏差在5%以内，在背风面的偏差在10%左右，在侧风面的偏差最大为15%～30%；对侧风面上风向的风压极值影响较为明显，尤其是2/3高度以上，随着测压管长的增大，侧风面上风向风压极值的最小值逐渐沿高度下移；测压管长对迎风面测点竖向相关性影响较小，侧风面测点风压相关性随测压管长的增大而增大，而背风面测点竖向相关性随测压管长的增大而减小。

Abstract:Simultaneous pressure measurement tests on the rigid model of the tall building with rectangular cross-section were carried out in a boundary layer wind tunnel in which pressure measurement tube lengths are 0-6, 0-8, 1-0, 1-2 and 1-5m respectively. Effects of the tube lengths on wind pressure characteristics of building surface and correlation of fluctuating wind pressure were investigated when the systematic correction of pressure measurement tubing system was not considered. The results show that the tube length has little effect on the mean pressure coefficients and greater influence on the fluctuating pressure coefficients. The deviations are within 5%, about 10%, and 15% to 30% for the fluctuating pressure coefficients on the windward, the leeward and sides, respectively. The tube length has an obviously effect on the peak pressures on the sides. The maximum pressure is gradually down along the model height with the increasing of the  tube length especially on the areas over 2/3 of the model height. The tube length has little effect on vertical correlation on the windward. Vertical correlation on the sides increases with the increasing of the tube length. However, vertical correlation on the leeward decreases with the  tube length increasing.
