| 摘 要： | 通过对武汉体育屋顶风洞试验上下表面同步测压数据的分析，研究了屋顶上下表面脉动风压的相关性及其和屋顶脉动风荷载之间的关系，并通过分析有关文献建议的脉动风压计算方法可能产生的误差，初步讨论了体育场大面积屋顶结构在抗风实验研究中上下表面非同步测压技术的可行性和可靠性，以及采用上下同步测压的必要性。

| Abstract: | The correlativity and the relationship of fluctuating pressures between up and down surfaces have been studied through analyzing the synchronous relational reference pressure data of Wuhan Stadium tested in wind tunnel.According to the calculating method suggested in the feasibility and reliability of asynchronous pressure measurement between up and down surfaces in wind tunnel tests are primarily discussed by error assessment and the necessity of synchronous pressure measurement is recommended as well. |
