摘要
基于风洞试验,研究了考虑周边干扰环境(建筑物)对大型冷却塔风荷载分布特性的影响。通过风洞试验得到了单塔和周边建筑物干扰下的冷却塔表面风压时程,分析了不同风向角下测压塔的最不利工况,给出了最不利风向角下的平均风压与脉动风压,结论可为考虑周边环境干扰情况下大型双曲线形冷却塔设计时风荷载的取值提供参考依据。
Based on the wind tunnel tests, compared wind load contains distribution effect characteristics of single and considering around interference buildings on large cooling tower. Through wind tunnel tests got cooling tower surface wind pressure for single tower and additional around interference building, analyzed different wind angle measuring pressure tower of most adverse workers condition, then analyzed the most adverse wind angle of average wind pressure and pulse wind pressure, got related conclusion which could provide guidance for designing wind load contains value in large cooling tower consider around interference.
